220 km. Rakesh started from Dehradun at 9.30 am at a speed of 40 Km/hour and Suresh started from Delhi after an hour at 50 Km/hour. Find out at what time they will meet.Solution
Suppose they meet x hours after 9:30 am Distance covered by Rakesh in x hours = 40x km Distance covered by Suresh in (x-1) hours = 50(x-1) km ∴ 40x+ 50(x-1) = 220 x=3 So they meet at 9:30 + 3 = 12:30 pm
