Given; Two buses 110 km apart travel toward each other. The first bus averages 20 km/h faster than the second bus and they meet each other after 1 hour.
To Find; Average speed of the first bus
Solution; Distance between two buses=110
Time=1hour
Let the speed of the first bus is x then the speed of the second one be x-20
Total distance=Soeed*Time
110=x-20+x
130=2x
Hence the speed of the first bus is 65 km/h
