1. A car travelled from Town A to Town B. At the same time,a bus travelled from Town B to Town A at a speed of 68 km/hr. After travelling half the journey, the car passed the bus.The car then took 21/4 hr to complete its journey. When the car reached Town B,the bus still had 37km to travel. Find the distance between Town A and Town B

Thanks

Bus has 37 km to travel when car completed the 2nd half of the journey
Extra time taken by the bus compared to the car = 37/68 hr
The car took 2 1/4 hour to travel 1/2 the distance
The bus took (2 1/4 + 37/68) hr to travel half the distance
Half the distance = 68 x (2 1/4+37/68) = 190 km
The full distance - 190 x 2 = 380 km
