Question

Мотоциклист проехал расстояние от города до посёлка за 3 часа со скоростью 40км/ч. Сколько времени понадобится велосипедисту, чтобы проехать 1/4 часть этого расстояния со скоростью 15км/ч.

Answer 1

40 × 3 = 120 км расстояние
120/4=30 км нужно проехать велосипедисту
30/15=2 ч времени понадобится велосипедисту, чтобы проехать 1/4 частьэтого расстояния 

Answer 2

Calculation of Time for the Bicyclist

To calculate the time it will take for the bicyclist to cover one-fourth of the distance at a speed of 15 km/h, we can use the formula:

Time = Distance / Speed

Given that the motorcyclist covered the distance from the city to the village in 3 hours at a speed of 40 km/h, we need to find one-fourth of that distance.

Let's calculate the time for the bicyclist:

1. Calculate the distance covered by the motorcyclist: - Distance = Speed × Time - Distance = 40 km/h × 3 hours - Distance = 120 km

2. Calculate one-fourth of the distance: - One-fourth of the distance = 1/4 × 120 km - One-fourth of the distance = 30 km

3. Calculate the time for the bicyclist: - Time = Distance / Speed - Time = 30 km / 15 km/h - Time = 2 hours

Therefore, it will take the bicyclist 2 hours to cover one-fourth of the distance at a speed of 15 km/h.
