A car accelerates uniformly from rest to a speed of 55 km/h (15 m/s) in 14 s. Find the distance the car travels during this time.

Multiply the average velocity, 7.64 m/s, by the time interval, 14 s.

Note: 55 km/h is actually 15.28 m/s, not 15.0

If they want the answer rounded to 2 significant figures, then using 7.5 m/s for the average velocity is OK
