Given : The distance between two cities M and N is 252 km.
A cyclist starts from M and a person walks from N at the same time.
The speed of the cyclist is 20 times that of the person who walks
Two hours later, both of them meet at a place.
To Find : how far is this place from the cities M and N.
Solution:
Let say speed of walk = X km/hr
Speed of cyclist = 20X km/hr
Distance = Speed x Time
Time = 2 hr
Distance covered by walk from N = 2X km
Distance covered by cyclist from M = 2 * 20X = 40X km
Total Distance covered = 2X + 40X = 42X km
42X = 252
=> X = 6
Distance rom N = 2* 6 = 12 km
Distance from M = 40 * 6 = 240 km
