Riya and George start walking towards each other from their houses at the speeds of 6 km/h and 8 km/h, respectively. After how long will they meet if the distance between their houses is 28 km.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2 h.
Given:
Speed of riya = 6 km/h
Speed of george = 8 km/h
Total distance between them = 28 km
Formula used:
Relative speed when the objects are moving in the opposite direction = S1 + S2
Where S1 and S2 are the speed of the objects
Speed = distance/time
Calculations:
Relative speed = 6 + 8 = 14
Required time = 28/14 = 2 h
