A river is 212 mile long. What is the length of the river on a map, if the scale is 1 inch : 50 miles?
RoseWind [281]

Answer:

4.24 inches

Step-by-step explanation:

1 inch / 50 miles = x / 212 miles      Cross multiply

1 inch * 212 miles = 50 miles * x      Divide by 50 miles

1 inch * 212 miles / 50 miles = x

x = 4.24 inches.

How much is 0.24 of an inch?

0.24 * 50 = 12

So 0.24 inches represents 12 miles.

Elina [12.6K]

1/2 * 140 = 140/2 = 70 square feet

The correct result would be 70 square feet.
