Question

Грузовик и легковой автомобиль едут навстречу друг другу по шосее скорость грузовика 60 км/ч что состовляет 5/6 скорость легковой машины сейчас растояние между ними 924 км через сколько времини оно сократится до 396 км

Answer 1

396:132 = 3.
Через 3 часа.

Answer 2

Calculating Time to Reduce Distance

To calculate the time it will take for the distance between the truck and the car to reduce from 924 km to 396 km, we can use the formula:

Time = Distance / Relative Speed

Where: - Distance is the initial distance between the truck and the car. - Relative Speed is the difference in speed between the truck and the car.

Relative Speed Calculation

The speed of the truck is given as 60 km/h, which is 5/6 of the speed of the car. To find the speed of the car, we can use the given information.

Given: - Speed of the truck = 60 km/h - Speed of the car = x (unknown) - Speed of the car is 6/5 times the speed of the truck

We can calculate the speed of the car using the given information.

60 * (6/5) = 72 km/h

So, the speed of the car is 72 km/h.

Time Calculation

Now that we have the speeds of the truck and the car, we can calculate the time it will take for the distance to reduce from 924 km to 396 km.

For the truck: - Time = 924 km / 60 km/h

For the car: - Time = 924 km / 72 km/h

Let's calculate the time it will take for both the truck and the car to cover the initial distance of 924 km.

For the truck: - Time = 924 km / 60 km/h = 15.4 hours

For the car: - Time = 924 km / 72 km/h = 12.8 hours

Now, let's calculate the time it will take for both the truck and the car to cover the reduced distance of 396 km.

For the truck: - Time = 396 km / 60 km/h = 6.6 hours

For the car: - Time = 396 km / 72 km/h = 5.5 hours

So, the time it will take for the distance to reduce from 924 km to 396 km is approximately: - Truck: 6.6 hours - Car: 5.5 hours
