Question

Попрыгунья прошла 240 километров за 8 часов ее скорость на четыре километра в час меньше чем скорость катера чему равна скорость катера

Answer 1

240/8=30(км/ч)-скорость попрыгуньи
30+4=34(км/ч)-скорость катера
Ответ: 34 км/ч скорость катера.

Answer 2

240:8=30км час
30+4=34км в час
ответ скорость катера 34км в час

Answer 3

Calculation of the Speed of the Boat

To find the speed of the boat, we can use the given information that the jumper traveled 240 kilometers in 8 hours and her speed is 4 kilometers per hour less than the speed of the boat.

Let's denote the speed of the boat as x kilometers per hour. According to the given information, the speed of the jumper is x - 4 kilometers per hour.

The formula to calculate the distance is:

distance = speed × time

For the jumper, the distance is 240 kilometers and the time is 8 hours:

240 = (x - 4) × 8

To find the value of x, we can solve this equation:

240 = 8x - 32

Simplifying the equation:

8x = 240 + 32

8x = 272

Dividing both sides of the equation by 8:

x = 34

Therefore, the speed of the boat is 34 kilometers per hour.

Answer

The speed of the boat is 34 kilometers per hour.
