Question

Аэросани за первые 3 часа проехал 240 км, а следующие 2 часа их скорость уменьшилась на 10 км/ч. Какое расстояние прошли аэросани за последние 2 часа

Answer 1

1)240:3=80(км) в час 2)80-10=70(км)в час 3)70*2=140(км)они проехали за 2 часа 4)240+140=380(км)расстояние Ответь:380

Answer 2

1.)240-10 = 230(км/ч) - скорость за последние два часа.
2.)230×2 = 460(км)
Ответ : 460 км.

Answer 3

Calculation of Distance Traveled by the Snowmobiles

To calculate the distance traveled by the snowmobiles in the last 2 hours, we need to first determine their initial speed and the speed at which their speed decreased.

Given: - The snowmobiles traveled 240 km in the first 3 hours. - The speed of the snowmobiles decreased by 10 km/h in the next 2 hours.

Let's break down the calculation step by step:

1. Calculate the initial speed of the snowmobiles: - The snowmobiles traveled 240 km in the first 3 hours. - Therefore, their initial speed can be calculated by dividing the distance traveled by the time taken: 240 km / 3 hours = 80 km/h.

2. Calculate the distance traveled in the next 2 hours: - The speed of the snowmobiles decreased by 10 km/h in the next 2 hours. - Therefore, their speed for the next 2 hours would be 80 km/h - 10 km/h = 70 km/h. - To calculate the distance traveled, we multiply the speed by the time: 70 km/h * 2 hours = 140 km.

Therefore, the snowmobiles traveled 140 km in the last 2 hours.
