A driver looks at a phone for 3 s while travelling at 72 km/h. How far does the car travel without the driver watching the road?
Answer and explanation
Correct answer: D. 60 m
- Step 1: Speed: m/s.
- Step 2: Distance m.
Answer
60 m.
Why not the others: 216 m is what you get if you treat km/h as m/s. 20 m is what you get if you count only one second. 80 m is what you get if you add an extra second.
