Mohan and Sohan are going from same place at 8 km/h and 9 km/h respectively. If Mohan and Sohan are going in the same direction, then what is the distance between Mohan and Sohan after 4.5 h ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 4.5 km
Given that
The speed of Mohan is 8 km/h.
The speed of Sohan is 9 km/h
The relative speed of them when they move in same direction = 9 - 8 = 1 km/h
Formula used
Distance between them = Relative speed × time
Calculation
⇒ 4.5 × 1 = 4.5 km
Hence, the required distance = 4.5 km
