Question

The time needed to travel a certain distance varies inverselywith the rate of speed. If it takes 8 hours to travel a certaindistance at 36 miles per hour, how long will it take to travel thesame distance at 60 miles per hour?3What equation rule represents the situation?

Answer 1

We have the following proportion:

`(8)/(36)=(x)/(60)`

solving for x:

`\begin{gathered} (8)/(36)=(x)/(60) \\ x=(60\cdot8)/(36) \\ x=13.3 \end{gathered}`

therefore, the trip will take a total of 13.3 hours
