Question

Find the distance, d, across the riverAssume that the ratio of d to 45 ft is the same as the ratio of 60 ft to 20 ft

Answer 1

To find the distance, d, across the river, we can set up a proportion using the given ratio:

d / 45 ft = 60 ft / 20 ft

Now, we can cross-multiply to solve for d:

d * 20 ft = 45 ft * 60 ft

Simplifying the equation:

20d = 45 * 60

20d = 2700

Dividing both sides by 20:

d = 2700 / 20

d = 135 ft

Therefore, the distance across the river, d, is 135 ft.
