Question

велосипедист За 5 часов проехал 65 км ,а мотоциклист за 4 часа проехал 208 км .Во сколько километров скорость мотоциклиста больше скорости велосипедиста? Во сколько раз скорость велосипедиста меньше скорости мотоциклиста?

Answer 1

65 / 5 = 13 км/ч

208 / 4 = 52 км/ч

52 / 13 = 4 во столько раз меньше и соответственно больше

хотя наверное в условии ошибка

а) НА сколько км скорость мотоциклиста больше 52-13= на 39 км

б) во сколько раз меньше 52 / 13 = 4 в 4 раза меньше

Answer 2

Calculation of Speeds

To find the difference in speeds between the cyclist and the motorcyclist, we need to calculate their respective speeds first.

Given: - The cyclist traveled 65 km in 5 hours. - The motorcyclist traveled 208 km in 4 hours.

To calculate the speed of each: - Speed = Distance / Time

Cyclist's Speed: - Distance = 65 km - Time = 5 hours - Speed = 65 km / 5 hours = 13 km/h

Motorcyclist's Speed: - Distance = 208 km - Time = 4 hours - Speed = 208 km / 4 hours = 52 km/h

Difference in Speeds

To find the difference in speeds between the motorcyclist and the cyclist, we subtract the cyclist's speed from the motorcyclist's speed.

Difference in Speeds: - Motorcyclist's Speed - Cyclist's Speed = 52 km/h - 13 km/h = 39 km/h

Therefore, the speed of the motorcyclist is 39 km/h greater than the speed of the cyclist.

Ratio of Speeds

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

Ratio of Speeds: - Motorcyclist's Speed / Cyclist's Speed = 52 km/h / 13 km/h = 4

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