Question

за 3 ч полета со ср.скоростью 240 км/ч вертолет пролетел такое расстояние,какое поезд может пройти за 12 ч.найдите ср.скорость движения поезда.

Answer 1

1)240:3=80(км)-за 1 год;

2)(80+12):2=46(км/год) 

Answer 2

Calculating the Distance Traveled by the Helicopter

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

Given: - Average speed of the helicopter = 240 km/h - Time of flight = 3 hours

Using the formula, the distance traveled by the helicopter can be calculated as: distance = speed × time distance = 240 km/h × 3 h distance = 720 km

The helicopter traveled a distance of 720 kilometers.

Calculating the Average Speed of the Train

To find the average speed of the train, we can use the formula: speed = distance / time.

Given: - Time taken by the train = 12 hours

Using the formula, the average speed of the train can be calculated as: speed = distance / time speed = 720 km / 12 h speed = 60 km/h

The average speed of the train is 60 km/h.
