Dilpreet drives a distance of 120 miles in 2 hours. She stops for 1 hour to eat lunch and rest. Then she drives another 150 miles in 3 hours.

What is Dilpreet’s average driving speed, in miles per hour, during her trip?

average speed for the whole trip  =  total distance / total time

 

total distance  =  120 miles + 150 miles  =  270 miles

total time  =  2 hours + 1 hour + 3 hours  =  6 hours

 

average speed  =  270 miles / 6 hours  =  45 miles / 1 hour

 

So her average speed is 45 miles per hour.  smiley
