Answer:
- Raja's speed = 30 km/hr.
- Distance between Raja's home and school is 12 km.
Therefore, Time = Distance/Speed
=> 12/30 = 2/5

- Ravi's speed = 35 km/hr
- Distance between Ravi's home and school is 10 kilometre.
Therefore, Time = Distance/Speed
=> Time = 10/35 = 2/7 hours.

Difference in the time:
=> 2/5 - 2/7
=> 4/35 = 0.11 hours approx.
Thats it!
