Answer:
Truck D.
Step-by-step 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,
[tex]v_A=\dfrac{300}{4}\\\\v_A=75\ mph[/tex]
Speed of Truck B,
[tex]v_B=\dfrac{240}{3}\\\\v_B=80\ mph[/tex]
Speed of Truck C,
[tex]v_C=\dfrac{325}{5}\\\\v_C=65\ mph[/tex]
Speed of Truck D,
[tex]v_D=\dfrac{170}{2}\\\\v_D=85\ mph[/tex]
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.
