Question
The graph shows how the velocity of a scooter varies with time in 50 s.
Work out: The distance traveled in 10 s, 20 s, and 50 s.

Solution
The distance travelled in 10 sec is S1 = `1/2`x20 x10 = 100 m
Distance travelled in 10s to 30s is s2 = 20 x (30 - 10) = 20 x 20 = 400 m Distance travelled in 30 s to 5os is S3 = `1/2` x20 x(50 - 30) = 200m.
Total distance covered by scooter is = 100 m + 400m + 200m =700m.
