Question

A cross country race car driver gets out on a 100-mile race. If the average speed is 60 mph, how long will it take to complete the race?

a) 1.5 hours
b) 2 hours
c) 2.5 hours
d) 3 hours

Answer 1

The time taken to complete a 100-mile race at an average speed of 60 mph is calculated using the formula time = distance ÷ speed, resulting in 1.67 hours, or approximately 1 hour and 40 minutes, so the correct answer is a) 1.5 hours.

Step-by-step explanation:

To calculate the time it will take for a cross country race car driver to complete a 100-mile race at an average speed of 60 mph, we use the formula time = distance ÷ speed. For a distance of 100 miles and an average speed of 60 mph, the time can be calculated as follows:

Time = 100 miles ÷ 60 mph = 1.67 hours, which is the same as 1 hour and 40 minutes (since 0.67 hours is approximately 40 minutes).

Therefore, the correct answer to the question is: a) 1.5 hours.
