The scatter plots shows the amount of time it took for 10 groups of different sizes to play a game of miniature golf.
how many groups completed the course in less than 90 minutes?

enter your answer in the box.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

a² + b²= c²

24² + 7² = c²

c= 25
