= 26.143 mph
b) Average speed = (26.143) (1.60934)
= 42.073km/h.
In most countries outside the United States speed is measured in kilometers per hour (Km/h)
rather than miles per hour(mph). Although the exact conversion from km/h to mph is 0.57, a
conversion factor of 0.6 is generally used because it is easier to remember. For the reverse
conversion a factor of 1.7 is normally used. Perform the following conversions using the
approximate conversion factors.
a) What is the speed in mph of an automobile on the German Autobahn travelling at 160
km/h?
b) What s the speed in km/h of motorcycle travelling at 70mph in the United States?
SOL:
a) 1 km/h = 0.6mph
160 km/h = (160) (0.6)
= 96 mph
