The american physical chemist gilbert newton lewis (1875-1946) proposed a unit of time called a jiffy. according to lewis, 1 jiffy is the time it takes light to travel 1 cm. (c= 2.998 x 10^8 m/s)

a) if you perform a task in a jiffy, how long does it take in seconds?

b) how many jiffys are in one minute?
