Distance travelled by the first car in 5 hours = 60 × 5 = 300 km Remaining distance = 550 - 300 = 250 km Time for both cars to meet = distance/(relative speed ) = 250/(60+40) = 250/100 = 21/2 hrs = 2 hrs 30 min ∴ Both the cars will meet after 2 hrs 30 min means (10 am + 2 hrs 30 min) = 12 hrs 30 min
