Question

The function h(t)=210-15t models the attitude of a hot air ballon 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

Hi there! The answer is h(10) = 60. h(10) means the height of the hot air balloon after 10 minutes.

We have the following function
$h(t) = 210 - 15t$

Filling in t = 10 gives
$h(10) = 210 - 15 \times 10 = 210 - 150 = 60$

Therefore, the height (h) of the hot air balloon after ten minutes (t = 10) is 60.
