Please Help - I'm Stupid

[Dakota120x]

I've been working on my summer packet and this was a problem I have do not know how to solve:

Kimberly, Billy, and Tommy took a ride. They went 105 miles in 90 minutes. Find the average speed in MPH.

I know this is probably easy for you but not for me. Thanks!!!

The average speed is the total distance divided by the total time. So divide the miles by the hours to get the average miles per hour.
