William runs 40 yards in 4.5 seconds. at the same pace how long will he take to run 100yards?

11.25 seconds

Step-by-step explanation:

first, we need to figure how how far william can run per second

we can find this by 40 ÷ 4.5

= 8.889 per second

so we know that 8.889 • s (seconds) = 100

8.889s = 100                 divide both sides by 8.889

s = 11.25 seconds

William will take 11.25 seconds to run 100 yards

Step-by-step explanation:

Constant Rate

William runs 40 yards in 4.5 seconds. The rate of change of the distance is

To run 100 yards, we divide by the rate obtained above:

William will take 11.25 seconds to run 100 yards

24

Step-by-step explanation:

because radius=1/2 of diameter
