Sheela walks a certain distance at (16/17)th of the usual speed and takes 5 minutes more than the usual time. Find the usual time taken. (in minutes)
Let usual speed = $$17$$ m/min and usual time taken = $$t$$ min
=> New speed = $$16$$ m/min and new time = $$(t+5)$$ min
Also, speed is inversely proportional to time.
$$\therefore$$ Usual time taken = 80 minutes
=> Ans - (C)
