Question

6. Craig and James both live 4 miles up a hill. Craig hikes uphill at a rate of 1 mile every two hours.
James tracks his own rate up the hill using the function: y = 2x + 2 where x is the number of hours he has
been hiking. Who is hiking faster? Explain.

Answer 1

Answer:

James

Step-by-step explanation:

James rate:

2x + 2 = 4

2x = 2

x = 1 hour

Rate = distance/time = 4/1 = 4 miles per hour

Craig's rate = 1/2 = 0.5 miles per hour

James is faster
