Question

Решите задачу: Туристы путь в 270км проделали,двигаясь 6 часов на теплоходе и 3 часа на автобусе. Какова была скорость теплохода, если она вдвое меньше скорости автобуса?

Answer 1

6*x+3*2x=270
6x+6x=270
12x=270
x=270:12
x=22,5км/ч скорость теплохода

Answer 2

Problem Analysis

We are given that tourists traveled a distance of 270 km, spending 6 hours on a steamboat and 3 hours on a bus. We need to find the speed of the steamboat, given that it is half the speed of the bus.

Solution

Let's assume the speed of the bus is x km/h. According to the problem, the speed of the steamboat is half the speed of the bus, so the speed of the steamboat is x/2 km/h.

To find the speed of the bus, we can use the formula: speed = distance / time.

The distance traveled on the steamboat is 270 km and the time spent on the steamboat is 6 hours. Using the formula, we can find the speed of the steamboat:

Speed of steamboat = Distance / Time = 270 km / 6 hours = 45 km/h.

Since the speed of the steamboat is half the speed of the bus, we can find the speed of the bus:

Speed of bus = 2 * Speed of steamboat = 2 * 45 km/h = 90 km/h.

Therefore, the speed of the steamboat is 45 km/h and the speed of the bus is 90 km/h.

Answer

The speed of the steamboat was 45 km/h.
