Question

2 Никита проехал 3ч на автобусе и 4ч на поезде.На сколько километров больше Никита проехал на поезде, чем на автобусе, еслискорость автобуса была 40 3/5 км/ч, а скорость поезда – 55 1/5км/ч?Ответ:​

Answer 1

Ответ:

на 99 км

Пошаговое объяснение:

220 4/5 - 121 4/5 = 99 км

Answer 2

To find out how many kilometers Nikita traveled more on the train than on the bus, we need to calculate the distances traveled by each mode of transportation.

Given: - Nikita traveled for 3 hours on the bus at a speed of 40 3/5 km/h. - Nikita traveled for 4 hours on the train at a speed of 55 1/5 km/h.

Calculating the distance traveled by the bus:

To calculate the distance traveled by the bus, we can use the formula: distance = speed * time.

The speed of the bus is 40 3/5 km/h, and Nikita traveled for 3 hours. Therefore, the distance traveled by the bus is: 40 3/5 km/h * 3 hours = 121 2/5 km.

Calculating the distance traveled by the train:

To calculate the distance traveled by the train, we can use the same formula: distance = speed * time.

The speed of the train is 55 1/5 km/h, and Nikita traveled for 4 hours. Therefore, the distance traveled by the train is: 55 1/5 km/h * 4 hours = 220 4/5 km.

Calculating the difference in distances:

To find out how many kilometers Nikita traveled more on the train than on the bus, we subtract the distance traveled by the bus from the distance traveled by the train.

220 4/5 km - 121 2/5 km = 99 2/5 km.

Therefore, Nikita traveled 99 2/5 kilometers more on the train than on the bus.
