Question

Из одного города одновременно в противоположных напровлениях выехали автобус и мотоцикл . Скорость автобуса 40 км / ч , мотоцикла - в 2 раза больше . Какое расстояние будет между ними через 3 часа ?

Answer 1

1) 40*2=80(км/ч)-скорость мотоцикла
2) 40*3=120(км)-проедет автобус за 3ч
3) 80*3=240(км)-проедет мотоцикл за 3ч
4) 120+240=360(км)-расстояние через 3ч
Ответ: 360 км

Answer 2

Calculation of Distance

To calculate the distance between the bus and the motorcycle after 3 hours, we need to determine the distance each vehicle has traveled in that time.

Given information: - Speed of the bus: 40 km/h- Speed of the motorcycle: 2 times the speed of the bus (80 km/h)

To find the distance traveled by each vehicle, we can use the formula:

Distance = Speed × Time

For the bus: Distance traveled by the bus = 40 km/h × 3 hours = 120 km

For the motorcycle: Distance traveled by the motorcycle = 80 km/h × 3 hours = 240 km

Therefore, after 3 hours, the bus will be 120 km away from the starting point, and the motorcycle will be 240 km away from the starting point. The distance between them will be the difference between their distances:

Distance between the bus and the motorcycle = 240 km - 120 km = 120 km

So, the distance between the bus and the motorcycle after 3 hours will be 120 kilometers.

Please note that the above calculation assumes constant speeds for both the bus and the motorcycle throughout the entire journey.
