13) If you are driving 72 km/h along a straight road and you look to the side for 4.0 s, how far do you travel during this inattentive period? A) 18 m C) 40 m 0 m B) 20 m

Solution

1 km/hr = 1000/3600 m/s = 5/18 m/s

72km/hr = 72 x 5/18 km/s = 20 m/s

Now, Distance = Speed x Time

Time = 4s

Distance = 20 x 4 = 80m.
