Here, OP, this should help

A) t is the time in hours

Miles traveled by H = Miles traveled by W
18+12t=16t
18=4t
4.5=t
It takes 4.5 hours to catch up

B)
Race is complete at 42 miles, Wanda catches up when t=4.5
18+12(4.5)=72

Wanda will not catch up

C)
Need to find when H reaches finish line then pick a constant speed for W

18+12t=42
t=2 for Hector to get to finish line

Solve for speed Wanda needs to get to finish line in 2 hours

2x=42
x=21mph
