3. A car and a bus are travelling towards each other. They are 510 km apart

at 13 20 and they pass each other at 16 20. If the car is travelling at a

Let the speed of the bus be x,

Distance = speed × time

(90+x) (16:20 –13:20) = 510

=> 3(90+x) = 510

=> 270 + 3x = 510

=> 3x = 510–270

=> x = 240/3

=> x = 80

Thus, the speed of the bus is 80km/hr.
