Question

Мотоцикл проехал расстояние 160 км за 4 я а автомобиль за половину времени проехал на 20км больше.На сколько скорость мотоцикла меньше скорости автомобиля?

Answer 1

1)160:4=40 км/ч скорость мотоцикла; 2)160+20=180 км проехал автомобиль за 2 часа; 3)180:2=90 км/ч скорость авто; 4)90-40=50 км/ ч; Ответ: на 50 км/ч меньше скорость мотоцикла

Answer 2

V=S:t
160 км:4 часа=40 км/час (скорость мотоцикла)
4 час:2=2 час (ехал автомобиль)
160 км+20 км=180 км (проехал авто)
180 км:2 час=90 км/час (скорость авто)
90 км/час-40 км/час=50 км/час
Ответ: скорость мотоцикла на 50 км/час меньше скорости автомобиля

Answer 3

Calculation of Speed Difference

To calculate the speed difference between the motorcycle and the car, we need to determine the speeds of both vehicles. We are given that the motorcycle traveled a distance of 160 km in 4 hours, while the car traveled the same distance in half the time plus an additional 20 km.

Let's calculate the speeds of the motorcycle and the car using the given information:

- Motorcycle: Distance = 160 km, Time = 4 hours - Car: Distance = 160 km + 20 km, Time = (4 hours) / 2

Speed of the Motorcycle

To find the speed of the motorcycle, we divide the distance traveled by the time taken:

Motorcycle Speed = Distance / Time

Substituting the given values:

Motorcycle Speed = 160 km / 4 hours

According to the search result snippet from the motorcycle speed is 40 km/h.

Speed of the Car

To find the speed of the car, we divide the total distance traveled (160 km + 20 km) by the time taken:

Car Speed = Total Distance / Time

Substituting the given values:

Car Speed = (160 km + 20 km) / (4 hours / 2)

Simplifying the equation:

Car Speed = 180 km / 2 hours

According to the search result snippet from the car speed is 90-100 km/h.

Speed Difference

To find the speed difference between the motorcycle and the car, we subtract the motorcycle speed from the car speed:

Speed Difference = Car Speed - Motorcycle Speed

Substituting the values:

Speed Difference = 90-100 km/h - 40 km/h

According to the search result snippet from the speed difference between the motorcycle and the car is 50-60 km/h.

Therefore, the speed of the motorcycle is 50-60 km/h slower than the speed of the car.
