A tortoise moves a distance of 100 metres in 15 minutes. What is the average speed of tortoise in km/h ?
A train travels the first 15 km at a uniform speed of 30 km/h; the next 75 km at a uniform speed of 50 km/h; and the last 10 km at a uniform speed of 20 km/h. Calculate the average speed for the entire train journey.
The speed of a moving object is determined to be 0.06 m/s. This speed is equal to :
Express the following in m s−1.
1 km h−1
Arrange the following speeds in increasing order.
10 m s-1, 1 km min-1 and 18 km h-1.
