Answer:
Step-by-step explanation:
here you need to draw a distance time graph for the car
like put 1-5 which indicates hours on x axis and
you need to covert the km into m by using the unitary method as we know 1km-1000m
then 40km=40000m and 20km=20000km like this 10-50 you need to convert in metres, then write them in y axis.
then you draw a graph for motion with constant speed in that distance time graph and plot them
then you will get your answer
