The speed of scooter, car and train are in the ratio of 1 : 4 : 16. If all of them cover equal distance then the ratio of time taken/velocity for each of the vehicle is:
Let the distance covered be 16 km, and the velocities be 1kmph, 4kmph and 16kmph.
Then the time taken: 16h, 4h, and 1h respectively
Ratio of time and velocity for each vehicle: $$\frac{16}{1}:\frac{4}{4}:\frac{1}{16}$$
=$$16:1:\frac{1}{16}$$
=256:16:1.
