Perhaps the question will be less confusing if you temporarily ignore the decimal parts, and just compare the whole-number parts.

Look at 74 , and then look at 7 .
Look at them again, and a few more times if necessary.
You'll see that 74 is waaay bigger than 7 .

That's true even when you stick the decimal parts back on.
The decimal parts can't change it ... a decimal part can't
add more than ' 1 ' to a whole number.

So 74 (plus any decimal) is still waaay bigger than 7 (plus any decimal).

2. The table below shows that the distance d varies directly as the time t. Find the constant of variation and the equation which describes the relation.

<h2><u>Solution</u>:-</h2>

Since the distance d varies directly as the time t, then d = kt.

Using one of the pairs of values, (2, 20), from the table, substitute the values of d and t in d = kt and solve for k.

$\sf{\rightarrow{d = kt}}$
