For example: A girl was driving about 66 miles. She startd at 2:48 and she wanted to get to the airport about 4:00 pm. How long will it take her??

If the question is the one I suggested in the comment, you can draw a diagram to solve this problem.

2:48 66miles 4:00

I couldnt draw a better picture since it does not support the drawing tools here. Basically, you draw a line with start and end points, label the time and the distance.

From given information, we have:

- Distance = 66 miles

- Time = 1h12' or 72 minutes

- Speed = distance/time = 66/72 miles/min

However, if we want to get the speed in miles/hour (m/h), we will multiply by 60 (1h = 60') to get 55m/h.

Hope that helps!

I guess your question would be" What is the speed of the girl so that she can get to the airport ontime?" since if she started at 2:48 and she wanted to get to the airport at 4:00PM, it would take her 1h 12' or 72 minutes.
