Question

A train travels at a constant speed of 24

Answer 1

Answer:

$d=24h$

Step-by-step explanation:

The table is

h        d

1        24

2       48

3       72

4       96

This relation can be presented as the following linear equation

$d=24h$

Because, the distance is defined as the product between the speed and the time. Also, we obtain this relation, by finding the slope of the given vales

$m=\frac{96-24}{4-1}=\frac{72}{3}=24$

Then, using one point, the slope and the point-slope formula, we have

$y-y_{1}=m(x-x_{1})\\y-24=24(x-1)\\y=24x-24+24\\y=24x$

Where $y=d$ and $x=h$.

Therefore, the expression that models this situation is

$d=24h$

Answer 2

Answer:

Step-by-step explanation:

d = 24 x h

since d is the distance in order to get that we need to multiply the speed times time and get the answer
