The tractor drove from point a to point b, at a speed of 18 km / h, after it drove 1.8 km, a motorcycle followed it, at a speed of 72 km / h. you need to find out how long it will take for the motorcycle to catch up with the tractor.

To determine the duration of the movement of the motorcycle after the tractor, we will use the formula: t = S / ΔV = S / (Vm – Vt).

Values of variables: S – initial distance between the tractor and the motorcycle (S = 1.8 km = 1800 m); Vm – motorcycle speed (Vm = 72 km / h = 20 m / s); Vt – tractor speed (Vt = 18 km / h = 5 m / s).

Let’s perform the calculation: t = S / (Vm – Vt) = 1800 / (20 – 5) = 120 s = 2 minutes.

Answer: The motorcycle can catch up with the tractor in 2 minutes.
