Vladimir is walking down the street at a speed of 4 miles per hour. Write an equation for the distance in miles, d, that Vladimi

zubka84 [21]

Answer:

$d=4t$

Step-by-step explanation:

We have been given that Vladimir is walking down the street at a speed of 4 miles per hour. We are asked to write an for the distance in miles, d, that Vladimir walks over time in hours, t.

We will use rate formula to solve our given problem.

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Distance}=\text{Speed}\times\text{Time}$

Upon substituting our given information in distance equation, we will get:

$d=4\cdot t$

$d=4t$

Therefore, the equation $d=4t$ represents the distance that Vladimir walks over time in hours.
