Hi,

Could someone assist on this question on Speed?

a) Mr Ho and Mr Lim started the journey from Town A and Town B respectively at the same time They walked towards each other.
If the average speed of Mr Ho was 4.5 km/h and they met at a place which was 5/11 of the whole journey and nearer to Town A.
Find the distance between A and B if Mr Lim took 5 hours to reach Town A.

Thank you for the help!

Hope this helps:

When they meet, Mr Ho travel 5/11 of the journey; so Mr Lim will have travelled 6/11 of the journey from town B.

so, for Mr Lim, whole journet takes 5h
6/11 => 5/11 x 6 = 30/11 h

For Mr Ho, Distance travelled (5/11) => 4.5 x 30/11 = 135/11 km

Distance between A & B (11/11) => 135/5 =27 km (ans)
