Answer:
0.94 ft/sec
Step-by-step explanation:
Airport: 2 feet per second.
Total distance 152 ft in the same amount of time it takes him to talk 72 feet on the pavement.
152/2 = 76 - This is how many seconds he was walking in the airport.
He walked 76 seconds and moved 152 feet.
So that means if the SAME time was used so 76 seconds he walked 72 feet, then we can do 72ft/76sec to get 0.94ft/sec

-6-1 = x+1-1
-7 =x
