Find the distance, d across the river. Assume the ratio of d to 75 ft is the same as the ratio of 40 ft to 20 ft. The distance across the river is _____ feet. is it 37.50?

It even tells you what the equation is ....
"the ratio of d to 75 ft is the same as the ratio of 40 ft to 20 ft." ---->d/75 = 40/20
d/75 = 2
d = 2(75) = 150
To find the distance, d, across the river, we can set up a proportion using the given ratios.
The ratio of d to 75 ft is the same as the ratio of 40 ft to 20 ft.
So, we can set up the proportion:
d/75 = 40/20
Now, we can cross-multiply to solve for d:
20 * d = 40 * 75
20d = 3000
Dividing both sides by 20:
d = 3000/20
d = 150
Therefore, the distance across the river, d, is 150 feet, not 37.50 feet.
To find the distance across the river, we can set up a proportion based on the given information.
Let's assume that the distance across the river is represented by the variable 'd'.
The given information tells us that the ratio of 'd' to 75 ft is the same as the ratio of 40 ft to 20 ft. We can express this as:
d/75 = 40/20
To solve for 'd', we can cross-multiply:
d * 20 = 75 * 40
Now, we can find the value of 'd' by dividing both sides of the equation by 20:
d = (75 * 40) / 20
Evaluating this expression:
d = 1500 / 20
d = 75
Therefore, the distance across the river, 'd', is 75 feet. It is not 37.50 feet.
