The car is moving at a speed of 54 km / h, find the distance that it will travel in 30 seconds.

Decision:

1) Find the vehicle speed in m / s:

60 minutes = 3600 seconds;

1 km = 1000 m.

V (speed) = S (distance) / t (time);

54000 m / 3600 sec = 15 m / s – the car covers 15 m in 1 second.

2) Let’s find the distance that the car will travel in 30 seconds:

S (distance) = V (speed) * t (time);

15 m / s * 30 sec = 450 m.

Answer: In 30 seconds, the car covers a distance of 450 m (S = 450 m).
