QUESTION 3. A car travels with a constant velocity of 45 km/hr for 20s. What distance does it cover in this time?
NECO 2005 Ans: 250m
Solutions:
Velocity = 45 km/hr = 45 x 1000/60 x 60 = 45000/3600 = 450/36 = 12.5m/s
Time = 20s
Distance = ?
Distance = Velocity x Time
Distance = 12.5 x 20
Distance = 250m
