Question

Помогите решить задачу ,к каждому действию объяснения- За 4 ч. автобус проехал 276 км, а грузовик- 212 км.На сколько скорость грузовика меньше скорости автобуса?

Answer 1

1) 276:4 =69 - ( км\ч ) - скорость автобуса 
2) 212:4= 53- (км\ч) - скорость грузовика 
3) 69-53 =16 (км \ч) - больше 
         Ответ : на 16 км \ ч больше скорость автобуса ,чем грузовика

Answer 2

1)276:4=69(км/ч)-скорость автобуса
2)212:4=53(км/ч)-скорость грузовика
3)69-53=16(км/ч)-меньше
ОТВЕТ:на 16 км меньше.

Answer 3

Problem Analysis

We are given that a bus traveled 276 km in 4 hours, and a truck traveled 212 km in the same time. We need to find the difference in speed between the truck and the bus.

Solution

To find the speed of each vehicle, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the bus and the truck.

Calculating the Speed of the Bus

The bus traveled 276 km in 4 hours. Using the formula, we can calculate the speed of the bus as:

Speed of the Bus = 276 km / 4 hours

Calculating the Speed of the Truck

The truck traveled 212 km in 4 hours. Using the formula, we can calculate the speed of the truck as:

Speed of the Truck = 212 km / 4 hours

Finding the Difference in Speed

To find the difference in speed between the truck and the bus, we subtract the speed of the truck from the speed of the bus:

Difference in Speed = Speed of the Bus - Speed of the Truck

Let's calculate the difference in speed.

Calculation

Using the given values, we can calculate the speed of the bus and the truck:

Speed of the Bus = 276 km / 4 hours = 69 km/h

Speed of the Truck = 212 km / 4 hours = 53 km/h

Now, let's find the difference in speed:

Difference in Speed = 69 km/h - 53 km/h = 16 km/h

Therefore, the speed of the truck is 16 km/h less than the speed of the bus.

Answer

The speed of the truck is 16 km/h less than the speed of the bus.
