Maria drives at a rate of 60 miles per hour. It takes her 3 hours to get to her aunt’s house. How long will it take if she drives at a rate of 50 miles per hour?

3.6hours

Step-by-step explanation:

Since speed=distance/time

But according to the question,the distance she travelled is not stated in the question

So we will have to determine that

Speed=distance/time

Distance=speed×time

Distance=60×3

=180miles

So to determine the time when she travels at 50miles per hour

It will be time =distance/speed

Time=180/50

=3.6hours

Therefore the time to travel at 50miles per hour is 3.6hours
