Question

the distance a boy travels while hiking is a function of how fast he hikes and how long he hikes at this rate. the boy usually maintains a speed of 4 miles per hour while hiking. let t represent the input variable. let h represent the function, and h(t)=4t the output variable. evaluate h(2) and write a sentence describing its meaning. write the result as an ordered pair.
h(2)= (simplify your answer.)

Explanation:

Step1: Substitute value of t

We are given the function $h(t) = 4t$ and we need to find $h(2)$. Substitute $t = 2$ into the function.
$h(2)=4\times2$

Step2: Perform multiplication

Calculate $4\times2$.
$h(2)=8$

Answer:

8

The ordered - pair is $(2,8)$. The meaning of $h(2) = 8$ is that when the boy hikes for 2 hours at a speed of 4 miles per hour, the distance he travels is 8 miles.
