Question

Из одного города одновременно в противоположных направлениях выехали автобус и грузовик. Через 4 часа после начала движения расстояние между ними составило 528 км. Скорость двидения автобуса 58 км/час. С какой скоростью двигался грузовик?

Answer 1

58*4=232
528-232=296
296/4=74

Answer 2

Problem Analysis

We are given that a bus and a truck started moving in opposite directions from the same city. After 4 hours, the distance between them was 528 km. We are also given that the speed of the bus is 58 km/h. We need to find the speed of the truck.

Solution

Let's assume the speed of the truck is x km/h.

Since the bus and the truck are moving in opposite directions, their speeds will add up to the relative speed between them. Therefore, the relative speed between the bus and the truck is 58 km/h + x km/h.

We know that distance = speed × time. After 4 hours, the distance between the bus and the truck is 528 km. Using this information, we can set up the following equation:

Distance = Speed × Time

528 km = (58 km/h + x km/h) × 4 hours

Simplifying the equation, we have:

528 km = (58 + x) × 4

Now, let's solve the equation to find the value of x.

528 = (58 + x) × 4

Dividing both sides of the equation by 4:

132 = 58 + x

Subtracting 58 from both sides of the equation:

x = 132 - 58

x = 74

Therefore, the speed of the truck is 74 km/h.

Answer

The truck was moving at a speed of 74 km/h.
