Roger bannister ran 5,280 feet in 4 minutes. (feet per second) (hint: 4 min=

22 ft/sec

Step-by-step explanation:

Find the unit rate in feet per min and then convert this result to feet per second:

5280 feet

= 1320 ft/min

 4 minutes

Then:                       1 min

1320 ft/min times   = 22 ft/sec

                                60 sec

i think that you should ask google for the answer to that problem because if we don't know it google does
