Question

At 8 a.m Ram travelled at an average speed of 50km/h from Town X to Town Y.

Half an hour later,Praha travelled at an average speed of 70km/h from Town Y to Town X along the same route. If town X and town Y are 205km apart, at what time did Ram and Praha pass by each other

 

Answer

Suggested answer:

Ram travelled at 50km/h.  Praha travelled at  70km/h.

At 8.30am, Ram travelled 25 km from Town X (50km/h x 1/2 hr).

Remaining journey to Town Y is,

205km – 25km = 180 km

50km/h + 70km/h = 120km/h

180 km / 120 km/h = 1.5hr.

Ans: They pass by each other at 10 am.
