Answer: 250 miles
Explanation:
I am not sure what grade level you are, but this is how it is done in college.
I hope it can give you an idea and be of some help.
First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.
150 minutes x 1 hour x 100 miles = 250 miles
60 mins. 1 hour
