Question

an airplane is traveling at 400 miles per hour. which equation can be used to find the total distance the plane will travel in $h$ hours?
$d = h + 400$
$d = 400 - h$
$d = 400 \times h$
$d = h \div 400$

Explanation:

Step1: Recall distance formula

The fundamental formula for distance is $\text{Distance} = \text{Speed} \times \text{Time}$.

Step2: Substitute given values

Here, speed = 400 miles per hour, time = $h$ hours, and distance = $d$. Substitute into the formula:
$d = 400 \times h$

Answer:

$d = 400 \times h$
