During a lawnmower race, a rider starts from rest and accelerates at 1 m/s/s for 10 seconds. The rider then maintains a constant velocity for the remainder of the race, which takes an additional 20 seconds.
A) How far was the race?
B) What was the lawnmower's average velocity for the race?

    distance= 1/2 *1*10 + 1*10*20

    average velocity= distance/30seconds

    check my thinking.
