Solution

Speed of bus =ukm/h

As we know that,

speed=DistanceTime

Distance = Speed × Time

Distance travelled by bus in 5 hours =u×5=5u

Distance left to reach chennai after 5 hours =20km

Therefore,

The distance of Chennai from Bengaluru = Distance traveled by bus in 5 hours + 20

Distance of Chennai from Bengaluru =5u+20

Hence the distance between Bengaluru and Chennai is (5u+20)km.
