Answer:
Step-by-step explanation:
acceleration, a = 20 m/s^2
initial velocity, u = 0 since it starts from rest
final velocity, v = 400 m/s
v = u + at
400 = 0 + 20 t
400 = 20 t
t = 400 / 20
<u><em>t = 20 sec</em></u>

ANSWER:
$18.90
EXPLANATION:
3L of fuel for every 100km

The slop would be 1/6.
you put it into slope intercept form (y=mx+b). parallel lines always have the same slope.
