Question

The track of a roller coaster is 1.265 miles long. The ride lasts for 2.3 minutes. What is the average speed of the roller coaster in miles per hour?

Answer 1

Answer:

0.7173 miles per hour

Step-by-step explanation:

divide 1.265 by 2.3

Answer 2

Answer : The average speed of the roller coaster is, 33 mile/hr

Explanation :

Average speed : It is defined as the ratio total distance to total time.

Formula used :

$\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}$

As per question,

Total distance traveled = 1.265 miles

Total time taken = 2.3 min = 0.038 hr    (1 hr = 60 min)

Now put all the given values in the above formula, we get:

$\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}$

$\text{Average speed}=\frac{1.265mile}{0.038hr}=33.3mile/hr\approx 33mile/hr$

Therefore, the average speed of the roller coaster is, 33 mile/hr
