If you are driving 110km and hour, how far do you travel in 2 seconds

60 seconds in 1 minute ... 60 minutes in one hr ... 60 * 60 = 3600 seconds/hr

110/3600 = x / 2 ... 110 km in 3600 sec = x km in 2 sec

cross multiply because this is a proportion

(3600) (x) = (110) (2)

3600x = 220

x = 220/3600

x = 0.0611 km/hr <==
