Divide both sides by 5 to get it down to the lowest bases.

16= 32 =48. 72- 48 = 24. The third side of the triangle is 24! Hope this helps, have a great day! :)
D is the answer to your question
The initial velocity is -150m/s.
Remember that:
V(t) = Vi + at, where v(t) is velocity at time t, Vi is initial velocity, and a is acceleration.
We know that the vehicle stopped after 30 seconds, so V(30) = 0.
Let's plug the useful info into our function and solve for a:
0 = -150 + a*30 Add 150 to both sides
150 = 30a Divide both sides by 30
a = 5 m/s²
The average acceleration is 5 meters per second squared.
