Question 62
A car travels 120 km in 4 hours. Calculate its average speed in m/sec. [Give your answer correct to one decimal place].
Solution
A car travels 120 km in 4 hours.
Distance =120 km = 120000 m [Because we know that 1 km = 1000 m]
Time = 4 hours = $$4\times3600$$ [Because we know that 1 hour = 3600 seconds]
= 14400 seconds
Speed = $$\frac{Distance}{time}$$
= $$\frac{120000}{14400}$$
= $$\frac{25}{3}$$
= 8.3 m/s (approx.)
