Given the speeds of each runner below, determine who runs the fastest.

Adam runs 9 feet per second.

Noah runs 164 feet in 14 seconds.

Jake runs 1 mile in 412 seconds.

Katie runs 845 feet in 1 minute.

Katie

Step-by-step explanation:

lets convert all the speeds to ft/1 sec

V adam: 9ft/sec

V noah: 164ft/14sec

164/14=11.7142857143 = around 11.7 ft/sec

V jake: 1 mile/412 sec

1 mile = 5280 ft

5280 ft/412 sec=

5280/412=12.8155339806 = around 12.8 ft/sec

V katie: 845ft/min

minute=60 sec

845ft/60sec=

845/60=14.0833333333 = around 14.1 ft/sec

now lets order the velocities (speeds) from least to greatest:

V adam: 9ft/sec, V noah: 11.7 ft/sec, V jake: 12.8 ft/sec, V katie: 14.1 ft/sec

thus, Katie is the fastest runner
