someone help fastttt !!!!!!!!!!!!!


A climber is on a hike. After hiking for 2 hours, he is at an altitude of 400 feet. After hiking for 6 hours, he is at an altitude of 700 feet. What is the average rate of change?

Respuesta :

Answer I think that it is x times 1 times 100= altitude.

Step-by-step explanation:

400/2= 200

but if you do it 700/6

it doesn't make sense unless

2 x 1 =2

2 x 100+200

I think the answer is 75 but I’m not sure
