Akash Leaves Mumbai At 6 Am And Reaches Bangalore At 10 Am . Prakash Leaves Bangalore At 8 Am And Reaches Mumbai At 11:30 Am. At What Time Do They Cross Each Other? |

Answer» Time taken by Akash = 4 h Time taken by Prakash = 3.5 h For your convenience take the product of times taken by both as a distance. Then the distance = 14km Since, Akash covers HALF of the distance in 2 hours(i.e at 8 am) Now, the REST half (i.e 7 km) will be COVERD by both prakash and akash Time taken by them = 7/7.5 = 56 MIN Thus , they will cross each other at 8 : 56am.
