Jason hiked 15.6 kilometers on saturday, 18.1 kilometers on sunday, and 22.7 kilometers on monday. how many kilometers did he hike during the three days?

a. 56.1
b. 48.7
c. 52.9
d. 56.4

The correct answer is D. 56.4

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Kilometers hiked by Jason on Saturday = 15.6

Kilometers hiked by Jason on Sunday = 18.1

Kilometers hiked by Jason on Monday = 22.7

2. How many kilometers did he hike during the three days?

Total of kilometers hiked by Jason = Kilometers hiked by Jason on Saturday + Kilometers hiked by Jason on Sunday + Kilometers hiked by Jason on Monday

Total of kilometers hiked by Jason = 15.6 + 18.1 + 22.7

Total of kilometers hiked by Jason = 56.4

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
