Question

Грузовой автомобиль прошёл 280 км за 4ч .А легковой 300км за 3ч.какой автомобиль ехал бистрее?

Answer 1

280:4=70км/ч скорость у первого автомобиля
300:3=100км/ч скорость у второго автомобиля
У второго больше

Answer 2

Найдем скорость автомобиля и грузового автомобиля
V = S/t
V = 280км/4ч=70 км/ ч  скорость грузового автомобиля
V = 300км/3ч=100 км/ ч  скорость автомобиля
100>70
автомобиль ехал быстрее

Answer 3

Calculation of Speed

To determine which vehicle was faster, let's calculate the speed of each vehicle.

The formula to calculate speed is:

Speed = Distance / Time

For the cargo truck: - Distance = 280 km - Time = 4 hours

Using the formula, we can calculate the speed of the cargo truck:

Cargo truck speed = 280 km / 4 hours = 70 km/h For the passenger car: - Distance = 300 km - Time = 3 hours

Using the formula, we can calculate the speed of the passenger car:

Passenger car speed = 300 km / 3 hours = 100 km/h

Comparison of Speeds

Comparing the speeds of the two vehicles, we can see that the passenger car was faster. The passenger car traveled at a speed of 100 km/h, while the cargo truck traveled at a speed of 70 km/h.

Therefore, the passenger car was faster than the cargo truck.
