Question

If a person travels at a speed of 28 m/s for 10 seconds, how far have they traveled?

Answer 1

It is a uniform rectilinear movement which is one in which an object moves in a straight line, in one only direction, with a constant speed.

When we spoke of constant speed we mean that the movement retains the same speed, that is; that the object does not move faster, or slower and always at the same speed.

If a person travels at a speed of 28 m/s for 10 seconds, how far have they traveled?

We obtain the data, as specified by the exercise.

Data:

V = 28 m/s

T = 10 s

D = ?

We have that the uniform motion formula is:

`\large\displaystyle\text{$\begin{gathered}\sf V=(d)/(t), \to where \end{gathered}$}`

• 
  `\large\displaystyle\text{$\begin{gathered}\sf V=Speed \end{gathered}$}`
• 
  `\large\displaystyle\text{$\begin{gathered}\sf D=distance \end{gathered}$}`

• 
  `\large\displaystyle\text{$\begin{gathered}\sf T=Time \end{gathered}$}`

We solve the formula, to calculate the distance and we obtain.And we also substitute our data.

`\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{d=v*t} \end{gathered}$} }`

`\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{d=28 \ \frac{m}{\\ot{s}}*10 \\ot{s} } \end{gathered}$}}`

`\boxed{\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{d=280 \ m } \end{gathered}$}}}`

The person travels a distance of 280 meters.
