Explanation / Answer

Part A) speed = distance/time taken = 1mile/(2.3 min) = 0.434 mile/min

but 1 min =1/60 hour

then speed is v = 0.434*60 = 26.1 mile/h

Part B) here i am taking the length of the football field is 110 m

then time taken is t = distance/speed = 110 m/(26.1 mile/h)= 0.0683 mile/(26.1mile/h)

t = 0.00261 hr = 9.42 s
