A car moves with constant velocity along a straight road. Its position is x1 = 0 m at t1 = 0 s and is x2 = 48m at t2 = 5.0s . Answer the following by considering ratios, without computing the car's velocity. What is the car's position at t = 2.5s ? What will be its position at t = 15s ?

Answer 1

x/2.5 = 48/5.0
and do the same for the other question.

Answer 2

okay so what's the answer

Answer 3

1.) 24m
2.) 144m
