Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour. What is Nina's rate in miles per hour if there are 5,280 feet in a mile? Which girl bikes faster?

convert feet to miles

63360/5280 = 12 miles

convert seconds to hours, there are 3600 seconds per hour

3400/3600 = 0.94 hours

since Nina rode 12 miles in 0.94 hours she is faster ( rode further in less time)
