Question

из села выехал мотоциклист со скоростью 32,8 км/ч. спустя 1,2ч вслед за ним выехал автомобиль,скорость которого в 1,8 раза больше скорости мотоцикла. какое расстояние будет между ними через 0,6ч после выезда автомобиля

Answer 1

32,8*(1,2+0,6)=59,04 расстояние которое проехал мотоциклист

32,8*1,8=59,04 скорость авто

59,04*0,6=35,424 расстояние которое проехало авто

59,04-35,424=23,616 расстояние между мотоциклом и авто через 0,6 часа.

Answer 2

Problem Analysis

We are given the following information: - A motorcyclist leaves a village with a speed of 32.8 km/h. - After 1.2 hours, a car leaves the village, and its speed is 1.8 times greater than the speed of the motorcycle. - We need to find the distance between them after 0.6 hours since the car left.

Solution

To find the distance between the motorcyclist and the car after 0.6 hours, we need to calculate the distances traveled by both the motorcyclist and the car during that time.

Let's calculate the distance traveled by the motorcyclist in 0.6 hours: - Speed of the motorcyclist = 32.8 km/h - Time traveled by the motorcyclist = 0.6 hours - Distance traveled by the motorcyclist = Speed * Time = 32.8 km/h * 0.6 hours = 19.68 km

Now, let's calculate the distance traveled by the car in 0.6 hours: - Speed of the car = 1.8 * speed of the motorcyclist = 1.8 * 32.8 km/h = 59.04 km/h - Time traveled by the car = 0.6 hours - Distance traveled by the car = Speed * Time = 59.04 km/h * 0.6 hours = 35.424 km

Therefore, the distance between the motorcyclist and the car after 0.6 hours since the car left is the difference between the distances traveled by the car and the motorcyclist: - Distance between them = Distance traveled by the car - Distance traveled by the motorcyclist = 35.424 km - 19.68 km = 15.744 km

So, the distance between the motorcyclist and the car after 0.6 hours since the car left is 15.744 km.

Answer

The distance between the motorcyclist and the car after 0.6 hours since the car left is 15.744 km.
