Question

The function h(t)=210-15t models the altitude of a hot air balloon over time t, in minutes. Explain what h(10) means in the context of the real-world

scenario, and how to find its value.

Answer 1

In real world context, h(10) would represent the height of the balloon above the ground. To find the value of h(10), substitute t with 10 in the equation

height = 210-15t

height = 210-15(10)

height = 210-150

height = 60
