Austin drove to a friends house 144 miles if he got there in three hours how fast was he driving

For this question, all you have to do is divide 144 by 3, or 144/3.

When you calculate it, your answer will be 48 mph.
                                                                 Always remember to put your units!
                                                                 mph= miles per hour
