The motorcyclist covered the distance between the two settlements in 30 minutes, while moving at a speed of 10 m / s. How long will it take for him to return if he moves at a speed of 15 m / s
To determine the time spent by the motorcyclist on the way back, we will use the equality: V1 * t1 = S (distance between settlements) = V2 * t2, whence we express: t2 = V1 * t1 / V2.
Values of variables: V1 – forward speed (V1 = 10 m / s); t1 – first time (t1 = 30 min); V2 is the speed of a given motorcyclist on the way back (V2 = 15 m / s).
Calculation: t2 = 10 * 30/15 = 20 minutes.
Answer: It will take 20 minutes for a given motorcyclist to return.
