Question

On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours. Find both the miles driven per hour and the hours driven per mile.

Answer 1

Miles driven per hour is 60 miles per hour

Hours driven per mile is 0.01667 hours per mile

Solution:

Given that,

On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours

Therefore,

Miles driven = 210 miles

`Time\ taken = 3(1)/(2)\ hour = (7)/(2) = 3.5\ hour`

To find: miles driven per hour and the hours driven per mile

Miles driven per hour

`(miles)/(hour) = (210)/(3.5)\\\\(miles)/(hour) = 60\ miles\ per\ hour`

Hours driven per mile

`(hours)/(miles) = (3.5)/(210)\\\\(hours)/(miles) = 0.01667\ hours\ per\ miles`

Thus both the miles driven per hour and the hours driven per mile are found
