Question

The La Jolla tide pools are 67.5 miles from the SLMS. A map shows that 2 inches = 15 miles. What distance is SLMS from the tide pools on the map?

Answer 1

Answer:

25

Step-by-step explanation:

because you have to divide by 15's

Answer 2

Answer:

9 inches.

Step-by-step explanation:

To find out what d (distance) is, make a proportion of the values you know and d. This would be 15/67.5 = 2/d.

¹⁵/₆₇.₅ = 2/d

Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by d.

d * (¹⁵/₆₇.₅) = 2

Expand 15/67.5   by multiplying both numerator and the denominator by 10.

d * (¹⁵⁰/₆₇₅) = 2

Reduce the fraction ¹⁵⁰/₆₇₅  to lowest terms by extracting and canceling out 75.

d * (²/₉) = 2

Multiply both sides by ⁹/₂, the reciprocal of ²/₉.

d = (2 * 9)/2

Cancel out 2 and 2.

d = 9

The distance between the SLMS from the tide pools on the map is 9 inches.
