Let d be distance travelled when they are level , and t = time that nora took to get level with mason
for Nora
6 = d/t
d = 6t
for Mason
5 = d / (t + 35)
d = 5 ( t + 350
so 6t = 5(t + 35)
solve for t
The sum of g and 3.
The sum of two values is added together.
g+3
You would add g to 3 since it is their sum the statement is asking for.
I hope this helps!

It’s a semicircle, so it would be 1/2 pi r^2.
