Answer 1

Answer:

20m/s

Explanation:

As we know in the above questions we are going to find the speed at which car is moving.

Therefore the

average Speed=Distance travelled/Time Taken

=400m/20s

=20m/s

Thus the car is moving at a speed of 20m/s.

thanks you.

Answer 2

Answer:

20 m/s

Explanation:

given

distance of the car travelling =400m

time taken to it. =20s

let the speed. = y

we know that

distance =speed×time

400. = y×20

y. =400/20

y =20 m/s
