Question

Answer

(a) Average speed of the bus = 300km / 5hr = 60 km/hr

(b) Average speed of the car = 300/km / 4 hr = 75 km/hr

If they meet at the point u km from town A,

u/75 = ( 300- u)/ 60

4u = 1500 – 5u

9u = 1500

u = 500/3

500/3/75 = 500/225 = 2 2/9hrs

They met each other at 2  2/9 hours.
