Question

The train 'A' travelled a distance of 120 km in 3 hours whereas, another train 'B' travelled a distance of 180 km in 4 hours. which train travelled faster?

Answer 1

Speed = distance/ time
so speed of A= 120km/3h
A's speed = 40 km/ hr.

Speed of B= 180km/4h
B's speed= 45km/hr.

Hence proved that 'B" moves faster.

Answer 2

Speed=distance/time taken

Speed of train a=120÷3=40km/h

Speed of train b=180÷4

                          =90÷2

                          =45km/h

The train b traveled faster
