How to solve this problem?
The circumfrench is 2pi*r.
the raduis is 225.
Then, remember that it's 40% of the circumfrence. :))
=^._.^=
How I can get 40% of the circumference of the whole circle?
40% is just 4/10 or .4
So you take the circumfrence and multiply by .4
:))
40% of a crcle's circumference = (4/10) * 2 pi = (4/5) pi
The total distance run / ft /s = time
So
[ 300 + 300 + (4/5) pi * 225 ] / 4 ≈ 291 seconds = 4 minutes 51 seconds
