Question

Велосепедист и мотоцыклист едут навстречу друг другу. Скорость мотоцыклиста 40 км/ч, а велосепедиста 12 км /ч . Через какое время они встретятся , если сейчас между ними 52 км? 156км?

Answer 1

40+12=52-скорость сближения.
52:52=1 час-через это время 
156:52=3 часа-через это время)

Answer 2

40+12=52-скорость сближения
52/52=1 час-через это время
156/52=3 часа-через это время

Answer 3

Calculation of Meeting Time

To calculate the time it takes for the cyclist and the motorcyclist to meet, we can use the formula:

Time = Distance / Relative Speed

Given that the distance between them is 52 km and the motorcyclist's speed is 40 km/h, while the cyclist's speed is 12 km/h, we can calculate the meeting time as follows:

For the motorcyclist: - Distance = 52 km - Speed = 40 km/h

For the cyclist: - Distance = 52 km - Speed = 12 km/h

Using the formula, we can calculate the meeting time for each of them:

Meeting time for the motorcyclist = 52 km / 40 km/h = 1.3 hours

Meeting time for the cyclist = 52 km / 12 km/h = 4.3 hours

Therefore, the motorcyclist and the cyclist will meet after approximately 1.3 hours or 1 hour and 18 minutes
