Question

how to find speed in kmph

Answer 1

If the speed is given in miles per hourmultiply it by 1.609. If the speed is measured in meters per second (m/s), multiply it by 3.6. For example, thespeed of 15 m/s corresponds to 15 x 3.6 or 54 km/h. Divide distance (in km) by the speed (in km/h) to calculate the time (in hours).
