Question

Средняя скорость вездехода 42км/ч, а аэросаней в 3 раза больше. Из города до станции нужно ехать 4ч на вездеходе и 3ч на аэросанях. Каково растояние от города до станции?

Answer 1

42*3=126 км/час скорость саней
4*42=168 км на вездеходе
3*126=378 км на санях
168+378=546 км от города до станции
===================

Answer 2

Calculation of the Distance from the City to the Station

To calculate the distance from the city to the station, we can use the formula:

Distance = Speed × Time

Given that the average speed of the tracked vehicle is 42 km/h and the average speed of the aerobus is three times greater, we can calculate the time it takes to travel from the city to the station using both vehicles.

The time taken by the tracked vehicle is 4 hours, and the time taken by the aerobus is 3 hours.

Let's calculate the distance using the formula mentioned above:

For the tracked vehicle: Distance_tracked = Speed_tracked × Time_tracked = 42 km/h × 4 h = 168 km.

For the aerobus: Distance_aerobus = Speed_aerobus × Time_aerobus = (42 km/h × 3) × 3 h = 378 km.

Therefore, the distance from the city to the station is 168 km when using the tracked vehicle and 378 km when using the aerobus.
