professor190 [17]

Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.

<h3>What is the together rate?</h3>

The together rate is the sum of each separate rate.

In this problem, the rates are:

Together: 1/8.

Mr Adam: 1/12.

Mrs Adams: 1/x.

Hence:

$\frac{1}{12} + \frac{1}{x} = \frac{1}{8}$

$\frac{x + 12}{12x} = \frac{1}{8}$

$12x = 8x + 96$

$4x = 96$

$x = \frac{96}{4}$

$x = 24$

If Mrs Adams camps alone, she will use all the water in 24 hours.

Ivan and Tanya share £150 in the ration of 4:1

Zarrin [17]

Answer:

Money Ivan gets extra = 120 - 30 (or 3x) = 90

Step-by-step explanation:

Ivan = 4x

Tanya = 1x

Total = 150

4x + x = 150

5x = 150 ; x = 150 / 5 = 30

Ivan = 4x = 120

Tanya = 1x = 30

Money Ivan gets extra = 120 - 30 (or 3x) = 90
