Question

Велосипедист за несколько часов проехал 36 км. сколько километров пройдёт за тоже время пешеход, скорость которого в 3 раза меньше скорости велосипедиста? б) сколько километров проедет за тоже время мотоциклист, скорость которого в 5 раз больше скорости велосипедиста?»

Answer 1

36 : 3 = 12 км пройдет пешеход.
36 × 5 = 180 км проедет мотоциклист

Answer 2

Calculating Distances for Pedestrian and Motorcyclist

To calculate the distances for the pedestrian and motorcyclist, we can use the formula: distance = speed × time. Given that the cyclist covered 36 km in a certain time, we can calculate the distances for the pedestrian and motorcyclist based on their respective speeds.

Pedestrian's Speed: The pedestrian's speed is 3 times slower than the cyclist's speed.

Using the formula distance = speed × time, we can calculate the distance the pedestrian will cover in the same time it takes the cyclist to cover 36 km.

Motorcyclist's Speed: The motorcyclist's speed is 5 times faster than the cyclist's speed.

Similarly, using the formula distance = speed × time, we can calculate the distance the motorcyclist will cover in the same time it takes the cyclist to cover 36 km.

Let's calculate the distances for the pedestrian and motorcyclist based on the given information.

Calculations

Pedestrian's Distance: The pedestrian's speed is 3 times slower than the cyclist's speed. Therefore, the pedestrian's speed is 1/3 of the cyclist's speed.

Given: - Cyclist's distance = 36 km - Cyclist's speed = v - Pedestrian's speed = v/3

Using the formula distance = speed × time, the pedestrian's distance can be calculated as: distance_pedestrian = (v/3) × time

Motorcyclist's Distance: The motorcyclist's speed is 5 times faster than the cyclist's speed. Therefore, the motorcyclist's speed is 5v.

Given: - Cyclist's distance = 36 km - Cyclist's speed = v - Motorcyclist's speed = 5v

Using the formula distance = speed × time, the motorcyclist's distance can be calculated as: distance_motorcyclist = (5v) × time

Let's calculate the distances for the pedestrian and motorcyclist based on the given information.

Results

Pedestrian's Distance: The distance the pedestrian will cover in the same time it takes the cyclist to cover 36 km is 12 km.

Motorcyclist's Distance: The distance the motorcyclist will cover in the same time it takes the cyclist to cover 36 km is 180 km.

Therefore, in the same time it takes the cyclist to cover 36 km, the pedestrian will cover 12 km and the motorcyclist will cover 180 km.
