If you run 100 m and 9.99 seconds and someone else runs in 12.0 seconds how many meters would you have beat them by?

Step-by-step explanation:

other runner runs in 12 seconds=100 m

runs in 9.9 seconds=100/12 ×9.9=990/12=330/4=165/2=82.5 m

you beat him by 100-82.5=17.5 m

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
