Justin and Ari go on a 30 km run. They usually run together at a speed of 10 km/h. If they start together but Justin runs at 12 his usual speed, and Ari runs at 112 times her usual speed, how many hours after Ari finishes will Justin finish?

a is the correct

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
