Question

Велосипедист за 5 часов проехал 65 км , а мотоциклист за 4 часа проехал 208 км . на сколько километров скорость мотоциклиста больше скорости велосипедиста? во сколько раз скорость велосипедиста меньше скорости мотоциклиста?

Answer 1

1) 65:5=13 км/ч - скорость велосипидиста
2)208:4=52 км/ч - скорость мотоциклиста
3)52-13=на39 км - больше скорость мотоциклиста
4)52:13 = в 4 раза - меньше скорость велосипедиста
Ответ: в 4 раза , на 39 км.
 

Answer 2

Calculating the Speeds of the Cyclist and the Motorcyclist

To find the difference in speed between the motorcyclist and the cyclist, we can calculate their respective speeds using the given distances and times.

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

Let's calculate the speed of the cyclist and the motorcyclist using the given distances and times.

For the cyclist: - Distance = 65 km - Time = 5 hours - Speed = 65 km / 5 hours = 13 km/h

For the motorcyclist: - Distance = 208 km - Time = 4 hours - Speed = 208 km / 4 hours = 52 km/h

Finding the Difference in Speed

Now, let's find the difference in speed between the motorcyclist and the cyclist.

The speed of the motorcyclist is 52 km/h, and the speed of the cyclist is 13 km/h.

The difference in speed is: 52 km/h - 13 km/h = 39 km/h

Calculating the Ratio of Speeds

To find the ratio of the motorcyclist's speed to the cyclist's speed, we can divide the speed of the motorcyclist by the speed of the cyclist.

The ratio of the motorcyclist's speed to the cyclist's speed is 52 km/h / 13 km/h = 4.

Therefore, the speed of the motorcyclist is 4 times greater than the speed of the cyclist.
