Question

помогите с задачей расстояние в 240км поезд может пройти за 4ч, а самолёт пролетит за 16мин. сколько километров проходит поезд за 1ч сколько километров может пролететь самолёт за 1мин

Answer 1

240:4=60км/ч

240:16=15км/мин

ответ машина 60км/ч, а самолет 15км/мин

Answer 2

240км:4ч=60км/ч скорость поезда

240км=240000м

240000м:16мин=15000м/мин=15км/мин скорость самолета

Answer 3

Problem Analysis

To solve this problem, we need to find the distance traveled by the train in 1 hour and the distance traveled by the plane in 1 minute. We are given that the train can cover a distance of 240 km in 4 hours and the plane can cover the same distance in 16 minutes.

Train's Speed

To find the distance traveled by the train in 1 hour, we can divide the total distance (240 km) by the total time taken (4 hours): Train's speed = Total distance / Total time = 240 km / 4 hours = 60 km/hour

Therefore, the train can cover 60 kilometers in 1 hour.

Plane's Speed

To find the distance traveled by the plane in 1 minute, we can divide the total distance (240 km) by the total time taken (16 minutes): Plane's speed = Total distance / Total time = 240 km / 16 minutes

However, we need to convert the time from minutes to hours to match the units of the train's speed. There are 60 minutes in 1 hour, so we can divide the total time (16 minutes) by 60 to get the time in hours: Total time in hours = 16 minutes / 60 = 0.2667 hours

Now we can calculate the plane's speed: Plane's speed = Total distance / Total time = 240 km / 0.2667 hours

Let's calculate the plane's speed:

240 km / 0.2667 hours = 900 km/hour (rounded to the nearest whole number)

Therefore, the plane can cover 900 kilometers in 1 hour.

To find the distance traveled by the plane in 1 minute, we can divide the plane's speed by 60 (since there are 60 minutes in 1 hour): Distance traveled by the plane in 1 minute = Plane's speed / 60 = 900 km/hour / 60 = 15 km/minute

Therefore, the plane can cover 15 kilometers in 1 minute.

Summary

In summary, the train can cover 60 kilometers in 1 hour, and the plane can cover 15 kilometers in 1 minute.
