135/180=x/40
solve by cross multiply
About 7,460 punds if you add everything together
This is an arith. sequence, and the common difference is -9.
a(n+1) = a(n)-9, with a(1)=8. Thus, if we look at the first term, we see 8; subracting 9 from 8 produces the second term (-1).
S = Speed
D = Distance
T = Time
S = D/T
S = 50m/1/2
50 divided by 1/2 = 25
25 = 50/1/2
S = 25 m/min.
