Question

A car moving at a constant speed travels $88$ $\text{feet}$ in $2$ $\text{seconds}$. Use a proportion to find how many feet it travels in one minute?

Answer 1

Step-1: Solve for the speed of car:

Given that car moving at a constant speed travels $88$ $\text{feet}$ in $2$$\text{seconds}$

We know that speed $\mathrm{s}=\frac{\mathrm{d}}{\mathrm{t}}$, where $\text{d}$ is the distance travelled in time $\text{t}$

Here $d=88\text{ft}.$ and $t=2\text{sec}.$

$\therefore s=\frac{88\text{ft}}{2\text{s}}=44\text{ft./sec}$

Step-2: Solve for the distance travelled by car in one minute:

$s=44\text{ft/sec}$ $\Rightarrow$the car travels $44\text{ft}$ in $1\text{second}$

$1\text{minute}=60\text{seconds}$

$\therefore$Distance travelled by car in $1\text{minute=}$Distance travelled by car in $60\text{seconds}$

$=44\times 60=2640\text{ft}.$

Hence, the distance travel by the car in one minute is $2640\text{ft}.$
