Answer 1

Truck D.

Explanation:

Below are the rates of travel of 4 shipping trucks.

Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.

Speed = distance/time

Speed of Truck A,

`v_A=(300)/(4)\\\\v_A=75\ mph`

Speed of Truck B,

`v_B=(240)/(3)\\\\v_B=80\ mph`

Speed of Truck C,

`v_C=(325)/(5)\\\\v_C=65\ mph`

Speed of Truck D,

`v_D=(170)/(2)\\\\v_D=85\ mph`

It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.
