Roger bannister ran 5,280 feet in 4 minutes (feet per second) ( hint 4 min = ? s) i don't get it plz

22 feet per second

Step-by-step explanation:

Hi, the question asks for the speed rate in feet per second.

Since 1 minute = 60 seconds, 4 minutes x 60 = 240 seconds.

So, he ran 5,280 feet in 240 seconds.

To calculate the speed rate in feet per second we simply have to divide the distance (5280) by the time (240):

5280 feet / 240 sec = 22 feet per second

Feel free to ask for more if needed or if you did not understand something.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
