Question

Mohit and Rohan travelled from Delhi to Jaipur. Mohit travelled at the speed of 150 km per 3 hours and Rohan travelled at the speed of 120 m per 8 seconds. Who will reach Jaipur first.

Answer 1

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
