Answer 1

Answer: Angle AOB is one of the central angles of the cylinder in Diagram 2. Since a cylinder has 360 degrees around, you can divide that by 5 (pentagon = 5 sides, 5 central angles) to get 72 degrees as the measurement of angle AOB.

Darius takes his family on an afternoon boat ride. Going through York Canal, he drives 5 miles in 15 minutes. Later on as he crosses Stover Lake, he drives 30 minutes at the same average speed. Which statement about the distances is true?

Answers

The distance traveled in the york canal is one-half the distance traveled on stover lake. The correct option is C.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that Going through York Canal, Darius drives 5 miles in 15 minutes. Therefore, the distance traveled by him in this time period is 5 miles. And his speed is,

Speed = Distance / Time

= 5 miles / 15 minutes

= (1/3) miles per minutes

Also, as he crosses Stover Lake, he drives 30 minutes at the same average speed. Therefore, the distance that is traveled by him is,

Distance = Speed × Time

= (1/3) miles per minute × 30 minutes

= 10 miles

Further, if we take the ratio of the distance of the two, then we can write,

$\frac{\text{Distance traveled in the York canal}}{\text{Distance traveled in Strover Lake}}= \rm (5\ miles)/(10\ miles)$

$\frac{\text{Distance traveled in the York canal}}{\text{Distance traveled in Strover Lake}}= \rm \frac12$

Distance traveled in the York canal = (1/2) Distance traveled in Strover Lake

Hence, The distance traveled in the york canal is one-half the distance traveled on stover lake.

The complete question is:

Darius takes his family on an afternoon boat ride. Going through the york canal, he drives 5 miles in 15 minutes. Later on, as he crosses stover lake, he drives 30 minutes at the same average speed. Which statement about the distance is true?

A : The distance traveled in the york canal is 15 miles less than the distance traveled on stover lake.

B : The distance in the york canal is twice the distance traveled on stover lake.

C: The distance traveled in the york canal is one-half the distance traveled on stover lake.

D: The distance traveled in the york canal and stover lake are the same.

Answer:

Step-by-step explanation:

Given that Darius takes his family on an afternoon boat ride.

First he drives 5 miles in 15 minutes.

Next he drives 30 minutes at the same rate i.e. 5 m/15 min or 20 miles/hour

Since speed is 20 miles/hour, it follows that he travels 10 miles in 30 minutes.

So the true statement is

he travels 10 miles in 30 minutes

Concept used:

Distance travelled = speed x time

Speed =average speed normally denoted by miles per bour

A kayaker paddles 2 km upstream in the same time that it takes to paddle 3 km downstream. The average speed of the current is 1 km/h. What is the average speed of the kayak in still water?I need the work as well pleasee!!

Answers

Let x represent speed of kayak in the still water.

We have been given that a kayaker paddles 2 km upstream in the same time that it takes to paddle 3 km downstream. The average speed of the current is 1 km/h.

Speed of kayak upstream would be speed of kayak in still water minus speed of the current that is $x-1$ .

Speed of kayak downstream would be speed of kayak in still water plus speed of the current that is $x+1$ .

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

Time taken to travel 2 km upstream would be $(2)/(x-1)$ .

Time taken to travel 3 km upstream would be $(3)/(x+1)$ .

Since both times are equal, so we can equate both expressions as:

$(3)/(x+1)=(2)/(x-1)$

Cross multiply:

$3(x-1)=2(x+1)$

$3x-3=2x+2$

$3x-2x-3=2x-2x+2$

$x-3=2$

$x-3+3=2+3$

$x=5$

Therefore, the average speed of Kayak in still water is 5 km per hour.
