Sally travels by car from one city to another. She drives for 30.0 min at 80.0 km/hr, 12.0 min at 105.0 km/hr, and 45.0 min at 40.0 km/hr, and she spends 15.0 min eating lunch and buying gas. A. Determine the average speed for the trip.
B. Determine the total distance traveled.

Answers

Answer:

A) The average speed for the trip is $v_(average) =53,53(km)/(h)$ .

B) The total distance traveled is $d_(total)=91\ km$ .

Explanation:

Knowing that 1 hour has 60 minutes, we have that for each part of the trip:

$v_(1)=80(km)/(h)\ t_(1)=0,5\ h$

$v_(2)=105(km)/(h)\ t_(2)=0,2\ h$

$v_(3)=40(km)/(h)\ t_(3)=0,75\ h$

$v_(4)=0(km)/(h)\ t_(4)=0,25\ h$

Total distance traveled

The distance traveled is the speed multiplied by a period of time. The total distance traveled is calculated adding up the speeds multiplied by the given periods of time.

$d_(total)=d_(1)+d_(2)+d_(3)$

$d_(total)=v_(1).t_(1)+v_(2).t_(2)+v_(3).t_(3)$

$d_(total)=80(km)/(h).0,5\ h+105(km)/(h).0,2\ h+40(km)/(h).0,75\ h$

$d_(total)=40\ km+21\ km+30\ km$

$d_(total)=91\ km$

B) The total distance traveled is $d_(total)=91\ km$ .

Average speed

The average speed could be calculated using the total distance traveled $d_(total)$ divided by the total time $t_(total)$ . We need to take into account the time spent eating lunch and buying gas.

$v_(average)=(d_(total))/(t_(total))$

$v_(average)=(v_(1).t_(1)+v_(2).t_(2)+v_(3).t_(3)+v_(4).t_(4))/(t_(1)+t_(2)+t_(3)+t_(4))$ $v_(average)=(91\ km)/(0,5\ h+0,2\ h+0,75\ h+0,25\ h)$

$v_(average)=(91\ km)/(1,70\ h)$

$v_(average)=53,53(km)/(h)$

A) The average speed for the trip is $v_(average) =53,53(km)/(h)$ .

Total distance = (30/60 x 80) + (12/60 x 105) + (45/60 x 40) = 0.5 x 80 + 0.2 x 105 + 0.75 x 40 = 40 + 21 + 30 = 91 km

Average distance = total distance / time taken = 91 / (30/60 + 12/60 + 45/60) = 91/ (0.5 + 0.2 + 0.75) = 91/1.45 = 62.76 km/hr

Answers

Bar charts are useful for displaying information segments and comparing categorical or discrete variables like age groups, classes, and schools, as long as there aren't too many categories.

What is the relationship between globular clusters and the milky way?

Answers

Globular clusters are nearly spherical groups of about 10,000 to 1 million stars. A typical galaxy may contain up to a few hundred globular clusters; our galaxy, the Milky Way, has somewhere between 125 and 200 globular clusters orbiting the galactic center.

The Sun and most stars are made almost entirely of a. hydrogen and carbon. b. helium and nitrogen. c. oxygen and nitrogen. d. helium and hydrogen.

Answers

So the question is what are the Sun and most stars almost entirely made of. So most stars, including our Sun are made out of hydrogen and helium. There is also a small percentage of oxygen, carbon and nitrogen and also very small quantities of iron, silicone and other metals. So the correct answer is d.
