Question

Hailey's family is driving to her aunt's house. The family travels 239.4 miles between the hours of 9:10 am and 1:40 pm. What equation can Hailey use to determine their average rate of travle R, rounded to the nearest mile per hour? Use the given numbers and operations to create an equation that represents the problem. Then, solve the problem

Answer 1

53.2mph

Explanation:

The average rate of travel is total distance traveled over total time.

`Average\:Rate=(Distance)/(Time)`

Total distance is 239.4 miles

Total time is 1:40pm-9:10am=13hrs:40mins-9hrs:10mins=4hrs:30mins or 4.5hrs

`Average\:Rate=(239.4)/(4.5)mph=53.2mph`
