Question

Speed of a car is constant at $60\text{miles/hr}.$ Generate the table to represent the distance covered verse the time required.

• A. Distance (miles) Time (hours)

  $90$	$1.5$
  $60$	$1$
  $30$	$0.5$
  $15$	$0.25$

• B. Distance (miles) Time (hours)

  $100$	$2$
  $75$	$1.5$
  $5$	$0.1$
  $15$	$0.3$

Answer 1

The correct option is A Distance (miles) Time (hours)

$90$	$1.5$
$60$	$1$
$30$	$0.5$
$15$	$0.25$

We know, $\text{Speed}=\frac{\text{Distance}}{\text{Time}}$
$\Rightarrow$ $\text{Time}=\frac{\text{Distance}}{\text{Speed}}$
$\Rightarrow$ $\text{Time}=\frac{\text{Distance}}{60\text{miles/hr}}$

To travel, $60\text{miles},$ time required $=\frac{60}{60}=1\text{hr}.$
Similarly, for $30\text{miles},$ time required $=\frac{30}{60}=0.5\text{hr}.$

Now, generate a $\text{Distance}$ verses $\text{Time}$ table. Distance (miles) Time (hours)

$90$	$1.5$
$60$	$1$
$30$	$0.5$
$15$	$0.25$

The ordered pairs are: $(90,1.5),(60,1.5),(30,0.5),(15,0.25)$
