Question

Велосипедист за 3 ч проехал 57 км,а мотоциклист за 2 ч проехал на 71 км больше.на сколько километров в час скорость велосипедиста меньше скорости мотоциклиста?

Answer 1

1)57:3=19 км/ч скорость велосипедиста
2)57+71=128 км проехал мотоциклист
3)128:2=64 км/ч
4) 64-19=45 км/ч скорость велосипедиста меньще скорости мотоциклиста
Ответ: на 45 км/ч

Answer 2

1) 57:3=19 (км\ч)-скорость велосипеда
2) 57+71=128 (км/ч)-путь мотоциклиста
3) 128:2=64 (км/ч)скорость мотоциклиста
4)64-19=45 (км/ч)
Ответ:на 45 км/ч скорость велосипеда меньше скорости мотоциклиста

Answer 3

Calculating the Speed Difference between the Cyclist and the Motorcyclist

To find the speed difference between the cyclist and the motorcyclist, we can use the formula: speed = distance / time

Given: - The cyclist traveled 57 km in 3 hours. - The motorcyclist traveled 71 km more than the cyclist in 2 hours.

Let's calculate the speed of both the cyclist and the motorcyclist.

Calculating the Speed of the Cyclist

The speed of the cyclist can be calculated using the formula: speed = distance / time

The distance traveled by the cyclist is 57 km, and the time taken is 3 hours.

So, speed of the cyclist = 57 km / 3 hours.

Calculating the Speed of the Motorcyclist

The distance traveled by the motorcyclist is 71 km more than the cyclist, and the time taken is 2 hours.

So, speed of the motorcyclist = (57 km + 71 km) / 2 hours.

Now, let's calculate the speeds of both the cyclist and the motorcyclist.

Calculations

- Speed of the cyclist = 57 km / 3 hours = 19 km/h- Speed of the motorcyclist = (57 km + 71 km) / 2 hours = 128 km / 2 hours = 64 km/h

Finding the Speed Difference

To find the speed difference, we subtract the speed of the cyclist from the speed of the motorcyclist.

Speed difference = Speed of the motorcyclist - Speed of the cyclist Speed difference = 64 km/h - 19 km/h = 45 km/h

Conclusion

The speed of the cyclist is 19 km/h, and the speed of the motorcyclist is 64 km/h. Therefore, the speed of the cyclist is 45 km/h less than the speed of the motorcyclist.
