Question

3. A train
traurels
120 km in 30 minutes. What is
average speed?​

Answer 1

Speed = Distance/Time

120km= 120000m

30minutes= 30×60s= 1800s

Therefore, the speed of the train=

120000m/1800s

=6.67m/s(approx.)

Note- Always prefer to give your answer in standard units. Standard unit of speed is m/s(for velocity also, it is m/s)
