Who is faster?
Kay [80]
Kendra is going faster. You could convert Kendra's measurement to feet per second by doing to following:

0.25 mi/1 min x 5280 ft/1 mi x 1 min/60 sec

Which equals:

(0.25)(5280)ft/60 sec

Simplify, and Kendra's speed is 22 feet per second.

mi= mile(s)
min= minute(s)
ft= feet
sec= second(s)
