A map shows the distance between Dallas and Houston as 3 inches. The actual distance is 240 miles. If there are 63,360 inches in a mile, find the ratio of the distance on the map to the actual distance between Dallas and Houston.
First, find the distance on the map in inches:
3 inches
Convert this to miles:
3 inches * (1 mile / 63,360 inches) = 0.00004717 miles
Now, calculate the ratio of the distance on the map to the actual distance:
0.00004717 miles / 240 miles = 0.0000001965
Therefore, the ratio of the distance on the map to the actual distance between Dallas and Houston is approximately 0.0000001965.
