A train travels 125.5 miles in 150 minutes 1 mike = 1.61 kilometers 1 hour = 60 minutes find the trains speed in kilometers per hour

Answers

Multiply 125.5 miles by 1.61 to get total kilometers:

125.5 x 1.61 = 202.055 kilometers total.

Divide 150 minutes by 60 to get total hours:

150/ 60 = 2.5 hours.

Now Divide total kilometers by total hours to get kilometers per hour:

202.055 kilometers / 2.5 hours = 80.822 kilometers per hour.

Round the answer as needed.

Answer:

80.822 km/hour

Step-by-step explanation:

A train travels in 150 minutes = 125.5 miles.

First we will convert 125.5 miles to kilometers

1 mile = 1.61 kilometers

125.5 miles = 125.5 × 1.61

= 202.055 kilometers

1 hour = 60 minutes

150 minutes = $(150)/(60)$

= 2.5 hours

Hence the train travels 202.055 kilometers in 2.5 hours.

Therefore, The speed of the train in one hour = $(202.055)/(2.5)$

= 80.822 km/hour

The trains speed is 80.822 km/hour.

What is 1/5 of 40???????????

Answers

Answer:
8

Explanation:
To get a fraction of a number, we will simply multiply this fraction by the number.

In the given we want to find $(1)/(5)$ of 40.

This can be computed as follows:
$(1)/(5)$ of 40 = $(1)/(5)$ * 40

= $(40*1)/(5)$

= $(40)/(5)$

= 8

Hope this helps :)

After calculating the fraction (one-fifth) of 40, the answer is 8.

What is the fraction (one-fifth) of 40?

To calculate one-fifth of 40, we divide 40 by 5. When we divide 40 by 5, we get the result 8. Therefore, the fraction (one-fifth) of 40 is equal to 8.

Let's break it down further to understand the process.

One-fifth represents dividing a whole into five equal parts. When we divide 40 by 5, we are essentially splitting 40 into five equal parts. Each part will be the same size.

To divide 40 by 5, we start with the number 40 and divide it by 5.

40 ÷ 5 = 8

The result, 8, represents one-fifth of 40. This means that if you take 40 and divide it into five equal parts, each part will be 8.

Therefore, 1/5 of 40 is equal to 8.

Sandy's orchard has only 4 apple trees for every 3 pear trees. She is wanting to plant enough avocado trees so that she has 2 avocado trees for every 5 trees. Sandy is planting 18 avocado trees, making the ratio of avocado trees be _ to _.

PLEASE HELP!

Answers

current ratio: 4 apple trees for every 3 pear trees. wants: 2 avocado trees for every 5 pear trees in the orchard. Sandy is planting 18 avocado trees so 2 avocado trees for every 5 pear trees =1 avocado trees for every 2.5 pear trees therefore if we have 18 avocado trees 18 x 2.5 = 45 pear trees 4 apple trees for every 3 pear trees 4/3 = 1.333 apple trees for every 1 pear tree therefore if we have 45 avocado trees 45 x 1.333 = 60 apple trees therefore ratio of avocado to apple trees = 18 : 60 18 : 60 = 9 : 30 = 3 : 10

On a car trip Sam drove m miles Kara drove twice as many miles as Sam and Darin drove 20 fewer miles than Kara in terms of m many miles did Darin drive

Answers

Answer:

Darin drove '2m - 20' miles.

Step-by-step explanation:

We are given that Sam drove 'm' no. of miles.

As, it is also given that Kara drove twice as many miles as Sam. Therefore we get that Kara drove '2m' no. of miles.

Now, it is given that Darin drove 20 miles fewer than Kara .i.e. Darin drove '2m - 20' no. of miles.

Hence, in terms of m, Darin drove '2m - 20' miles.

mount Whitney is 14,494 feet above sea level. Death Valleyis 282 feet below sea level what is the difference between these two elevations

Answers

Answer:

Describe each as below sea level, at sea level, or above sea level.

Death Valley sits at an elevation of –282 feet.

✔ below sea level

The elevation of Mount Whitney is 14,494 feet.

✔ above sea level

The elevation of the Singapore Strait is 0 feet.

✔ at sea level

If sea level is 0, and Mt. Whitney is 14,494 ft. above sea level. The difference between those two elevations is 14,494 feet. If death Valley is 282 feet below sea level, add the two to get the total distance away from each other. Your answer is 14,776.
