Answer:
Velocity of Mohit = 150 km per 3 hrs
= 150/3 km/hr
= 50 km/hr
Velocity of Rohan = 120 m per 8 sec
= 120/8 m/sec
= 15 m/sec
= 15 × 18/5 km/hr
= 54 km/hr
Because we know that to convert m/sec into km/hr we multiply it by 18/5
hence Velocity of Rohan is more than Mohit so he reaches Jaipur first
