tim and joe started from time house at the same time. tim drove borth at 60 miles per hour, while joe drove east at 45 miles per hour. How far apart were they after 3 hours?

Speed of Tim = 60 miles/hour

Speed of Joe = 45 miles / hour

Distance = Speed x Time

A 3 hours, Tim had travelled 60 x 3 miles = 180 miles.

At 3 hours, Joe had travelled 45 x 3 miles = 135.

The difference between the distances is 45.

Therefore, they were 45 miles apart after 3 hours.

I hope this is right.
