Given:
Distance = 108 m
Time taken = 12 seconds
To Find:
The speed in km/h
Solution
Find the distance in km:
Distance = 108 m
Distance = 108 ÷ 1000 km
Distance = 0.108 km
Find the time in seconds:
Time Taken = 12 seconds
Time Taken = 12 ÷ 60 ÷ 60 hours
Time Taken = 1/300 hour
Find the speed:
Speed = Distance ÷ Time
Speed = 0.108 ÷ 1/300
Speed = 0.108 x 300
Speed = 32.4 km/h
Answer: The speed is 32.4 km/h
