b. How many people are in the museum after 10 hours?

Question

this is part b from my last question

here is the full question:

The graph below shows the rate of change for the number of people in a museum 𝑡 hours after it opens.

a. How many people are in the museum after 5 hours?

b. How many people are in the museum after 10 hours?

Answer 1

I can't see the graph, but the number of people in the museum after 5 hours would be the area under the curve from x = 0 to x = 5. For 10 hours, it will be the area under the curve from x = 0 to x = 10.
