12 Lura is a lifeguard at a pool. She earn $369 for 3 hours of lifeguarding. How much does she earn
per hour ?

I think it's $123

Step-by-step explanation:

because it says how much does she earn per hour.

so I solved it by 369÷3=123.

not sure tho but that's my answer.

90% rotation

step-by-step explanation:

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.
