Question

От автовокзала одновременно отъехали автобус и автомобиль, и поехали в одной направлении по шоссе, скорость автобуса равна 50км/час, а скорость автомобиля в двое больше. На сколько км авбтобус отстанет от автомобиля через три часа?

Answer 1

50х2=100 км/ч - скорость автомобиля
(100-50)х3=150 км - отстанет автобус за 3 часа

Answer 2

Problem Analysis

To solve this problem, we can use the formula: distance = speed * time. We'll calculate the distance covered by the bus and the car after three hours and then find the difference to determine how far the bus is behind the car.

Calculations

The speed of the bus is 50 km/h, and the speed of the car is twice that, which is 100 km/h.

The distance covered by the bus after 3 hours is: distance_bus = speed_bus * time = 50 km/h * 3 h = 150 km

The distance covered by the car after 3 hours is: distance_car = speed_car * time = 100 km/h * 3 h = 300 km

Conclusion

So, after three hours, the bus will be 150 kilometers behind the car.
