Last Saturday, Felix and Kia went hiking in the mountains. When they started
back to the head of the trail at 2:00 pm, their elevation was 3,560 feet above
sea level. At 5:30 pm, their elevation was 2,390 feet. What was the rate of
change, to the nearest whole foot, of their elevation between 2:00 pm and 5:30
pm?

Respuesta :

Nit 100% sure.
I think rate of change is 334ft
r=distance/time
time: 5:30-2:00=3.5
distance: 3560-2390=1170 ft
r=1170/3.5
r=334 ft
