Question

janta experss run at a speed of 153 km per hour . what is speed in : metre per min ?

Answer 1

speed = 153 km /hr
because 1 km = 1000 m and 1 hr = 60 min.
so keep 1000 in place of km and keep 60 in place of hr.
(153 × 1000 ) / 60 = (153 × 100) / 6 = 2550 m/min.

Answer 2

2550 m/min is the correct answer
