Answer 1

Hi Hargun,

You can use ratios to solve this problem. If Jim reads 7 pages in 10 minutes, we can write that as a ratio like this:

7 pages / 10 minutes

We want to know how many pages he can read in 15 minutes, if he reads at the same rate. We can write a ratio for this, too, and use the letter x for the unknown number of pages:

x pages / 15 minutes

Now set the ratios equal to each other (since Jim is reading at the same rate).

7 / 10 = x /15

Then cross-multiply (one denominator by the other numerator, the other denominator by the opposite numerator).

10x = 105

Then solve for x.

x = 105/10 = 10.5

Jim will read 10.5 pages in 15 minutes (if he reads at a constant rate).
