Question 65
A train travels for 2 hours at a speed of 6 m/sec. What is the distance covered by the train in the mentioned duration of time?
Solution
A train travels for 2 hours at a speed of 6 m/sec.
time = 2 hours
speed = 6 m/sec
= $$\frac{6\times\ 3600}{1000}$$ km/h [we know that 1 km = 1000 m and 1 hour = 3600 seconds.]
= $$\frac{6\times\ 36}{10}$$ km/h
= $$\frac{216}{10}$$ km/h
= 21.6 km/h
distance covered by the train in the mentioned duration of time = speed $$\times$$ time
= $$21.6\times2$$
= 43.2 km
