Given:

An engineer traveled 130 mi by car and then an additional 690 mi by plane. The rate of the plane was three times the rate of the car. The total trip took 6 h.

Find the rate of the car.

Formula for the rate of the car:

v = d/t

v = velocity

d = distance

t = time

Solution:

Divide 6 h by 3 to determine the time for the car trip.

= 6h/3

= 2 h

Divide the distance traveled by the car by 2, to determine its rate.

= 130 mi/2h

= 65 mi/h

Final answer:

The rate of the car is 65 mi/h.
