Answer 2

In context to question asked,

We have to determine that,

How much words does Christopher can type in 7 minutes.

From the question,

It is given that,

Christopher types 450 words in 30 minutes,

So, for determining that,

How much words can he type in 1 minutes we will divide the number of words he types in 30 minutes by 30 minutes.

So, dividing 450 by 30,

We will get $=\frac{450}{30} = 15\:words$

So, Christopher can type 15 words in 1 minutes.

So, for finding that how much words does he type in 7 minutes,

We will multiply the number of words which he type in 1 minutes by 7.

So, we will get,

$=(7\times 15) = 105\:words$

Hence, we can type 105 words in 7 minutes.
