Question

A bug travels at the rate of 3.0 miles/hour. How fast is this in m/nsec? Hint: 2.54 cm = 1 inch and 1 mile = 5,280 feet

Answer 1

First, convert miles to meters

 

(3 miles/hour) * (5280 ft/mile) * (12 in/ft) * (2.54 cm/in)*(1 m/100 cm) * (hr/3600 seconds) * 1 second/10⁹ nanoseconds = 1.3411  * 10^-9 m/nsec
