If 2 liters of sea water contain 70 grams of salt, how much salt is in 32 liters of sea water?
OLga [1]

Answer:

1120 grams

Step-by-step explanation:

The amount of sea water is directly proportional to the amount of salt in the water.

Let the amount of sea water be W and the amount of salt be S.

This means that:

W α S

=> W = kS

where k = constant of proportionality

2 liters of sea water contain 70 grams of salt Therefore:

2 = k * 70

k = 2 / 70 = 1/35

Therefore, for 32 liters of sea water:

32 = 1/35 * S

S = 35 * 32

S = 1120 grams

There are 1120 grams of salt in 32 liters of water.

Elden [556K]

In the given diagram, it would be observed that each side of the bigger triangle are multiplied by a factor of \frac{1}{3} to give the values of each corresponding sides of the smaller triangle. But the included angle of the two triangles are the same.

Therefore, the reason why the triangles are similar is because of side-angle-side (SAS) relations. The correct option is B.
