Answer:
mmmmmmmmmmmmmmmmmmmmmmmmmm
Step-by-step explanation:
Joan's remaining distance is reduced by (600 ft)/(3 hours) = 200 ft/hour. She starts with 1600 ft remaining, so her distance remaining (y) after x hours is
.. y = -200x +1600
In order for the distance remaining to be zero, you must have
.. 0 = -200x +1600
.. 200x = 1600
.. x = 1600/200 = 8
It will take Joan 8 hours to hike 1600 ft.
.300, .375, .387
since these three numbers increase along the base of 300

Another way to figure the cost is $2.50 plus $0.50 per hour.
For 8 hours, the cost is $2.50 +8*$0.50 = $6.50.
