If a man is walking at a speed of $40\ m/min$ to cover a distance of $2\ km$, how much time would he take to do the same?
Here given, speed $=40\ m/min$
Distance $=2\ km=2000\ m$
Let $t$ be the time taken to cover the distance.
As we know $speed-distance$ formula: $speed =\frac{distance}{time}$
Or $40\ m/minute=\frac{2000\ m}{t}$
Or $t=\frac{2000\ m}{40\ m/min}$
Or $t=50\ minute$
Therefore, it would take $50\ minutes$ to cover the distance of $2\ km$ if a man walks with the speed of $40\ m/minute$.
