The distance between two cities A and B is 330 km. A cyclist starts from A at 8 am. and travels towards B at 60 km/hr. Another cyclist starts from B at 9 am. and travels towards A at 75 km/hr. At what time do they meet?

• Effective speed =60+75=135km/hr
  A travelled for 1 hour alone,so A covered a distance of 60 km in 1 hr.
  Remaining Distance=270km
  Time taken to meet=270/135=2 hr
  so they meet at 9a.m +2 hr=11 a.m

• ans:11am
  trial and error method
  In 1hour distance covered by A is 60 kms and by B it is 75kms
  so 60*x+75*y=330
  x=3,y=2
