A truck covered 280 km in 8 hours, and a passenger car covered the same distance in 4 hours.

A truck covered 280 km in 8 hours, and a passenger car covered the same distance in 4 hours. How fast is the speed of a truck less than that of a passenger car?

Let’s determine what speed the truck had, knowing that this vehicle covered 280 kilometers, spending 8 hours on this path:
1) 280: 8 = 35 km / h this speed of the truck;
Let’s determine what speed the car had, knowing that this car covered the distance of 280 kilometers in 4 hours:
2) 280: 4 = 70 km / h this is the speed of a passenger car;
Let’s determine how many times the speed of a truck is less than the speed of a car:
3) 70: 35 = 2 – twice the speed of the truck is less.
Answer: The speed of a truck is two times less than the speed of a passenger car.
