For 2 hours, Lia drove at the speed of 60 mph, and for the next 3 hours, at the speed of 50 mph. What was Lia's average speed during this trip?

A) 53 MPH

B) 54 MPH

c) 55 MPH

D) 56 MPH

E) 57 MPH

For 2 hours, Lia drove at the speed of 60 mph = 2 x 60 = 120 miles for 2 hours

The next 3 hours, at the speed of 50 mph = 3 x 50 = 150 miles for next 3 hours

Total 5 hours = 120 + 150 = 270 miles

Average = 270 miles / 5 hours = 54 miles per hour (MPH)

Answer:

B) 54 MPH
