Hector is competing in a 42 mile bicycle race. He has already completed 18 miles of the race and is traveling at a constant spee
d of 12 miles per hour when Wanda starts the race. Wanda is traveling at a constant speed of 16 miles per hour. Write and solve an equation to find when Wanda will catch up to Hector. Will Wanda catch up to Hector before the race is complete? Explain. At what constant speed would Wanda travel to catch up with Hector at the finish line? Explain.

Answer:
A, C, E
Step-by-step explanation:
From the table you can see that the water depth cahnges
for every
of snow (option B is false).
This means that the function modelling this situation is linear function (option A is true and option D is false). Let the equation of this function be Then
Subtract these two equations:
Hence,
The equation of the straight line (the graph of linear function) is (option E is true) This line passes through the point (0,0), because its coordinates satisfy the equation (option C is true).
