Rita takes 20 minutes to cover a distance of 3.2 kilometres on a bicycle . Calculate her speed in units of kilometer/min and metre/min.

Priyanka takes 30 minutes to cover a distance 3 kilometres on a bicycle. Calculate her velocity units of kilometre/min, m/s, and km/h.

Salma takes 15 minutes from her house to reach her school on a bicycle. If the bicycle has a speed of 2m/s, calculate the distance between her house and the school?

Suppose the two photographs, shown in fig.13.1 and fig 13.2, had been taken at an interval of 10 seconds. If a distance of 100 metres is shown by 1 cm in these photographs, calculate the speed of the blue car.

The distance between two stations is 240 km. A train takes 4 hours to cover this distance. Calculate the speed of the train?

After covering a distance of 30 km with a uniform speed there is some defect in a train engine and, therefore, its speed is reduced to 4/5 of its original speed. Consequently, the train reaches its destination late by 45 minutes. Had it happened after covering 18 kilometres more, the train would have reached 9 minutes earlier. Find the speed of the train and the distance of journey.
