Answer:
102.6666... feet in one second 1232 feet in twelve seconds.
Step-by-step explanation:
Most clear way of solving this breakdown the proportions by keep the value.
1 mile = 5280 feet.
1 hour = 60 minutes = 3600 seconds -- See now it is easy.
Feet per second...
= feet/seconds
(70*5280) = 369,600/3,600 = 102.666666667 -- That is 102.66...feet per second.
For twelve seconds just multiply by 12.
102.666666667*12 = 1232 feet in twelve seconds.
