Question

HURRY!! A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. What is the rate of change.

Answer 1

total distance =700+400ft

time =2+8 =10hour

rate =distance/time=1100/10=110 ft/hour

since he stops two times

rate of change =110/2=75ft/hour

Answer 2

175ft an hour

Step-by-step explanation: lets say t=hours

so 2t=400ft and 6t=700ft

the difference between hours is 4 because 6-4=2

so we would multiply 4 by ?

to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour
