Q. 21

# Mehak was moving through the city roads towards her school by a car. She recorded the odometer reading of the car after every five minutes and plotted a graph for distance vs time. She then inferred about the type of motion and found average speed from the graph.(a) Which qualities of Mehak are worth mentioning?(b) What type of motion would she have inferred?(c) How is average speed calculated from the graph?

(a) Mehak is curious, practical, skilled, alert and enthusiastic.

(b) Data given is insufficient to decide what kind of motion she infers.Motion can be uniform or non-uniform.

(c) Average speed =

And total distance travelled is given by the area under the velocity v/s time graph

Hence,

Average speed =
