Question

Расстояние между двумя поселками автобус проезжает за 4 часа со скоростью 30 км/ч. С какой скоростью должен ехать автобус, чтобы проехать это расстояние за 2 часа?

Answer 1

Нужно 1) 30*4=120 2)120:2=60(км/ч). Ответ. Со скоростью 60км/ч

Answer 2

1)4*30=120 (км)- расстояние между посёлками
2)120:2=60 (км/час)- должна быть скорость автобуса
Ответ:60км/ч

Answer 3

Calculation of Speed

To calculate the speed at which the bus should travel to cover the distance between the two villages in 2 hours, we can use the formula:

Speed = Distance / Time

Given that the bus takes 4 hours to cover the distance at a speed of 30 km/h, we can calculate the distance using the formula:

Distance = Speed x Time

Substituting the values, we have:

Distance = 30 km/h x 4 hours = 120 km

Now, to find the speed at which the bus should travel to cover this distance in 2 hours, we can rearrange the formula:

Speed = Distance / Time = 120 km / 2 hours = 60 km/h

Therefore, the bus should travel at a speed of 60 km/h to cover the distance between the two villages in 2 hours.
