Question

The cities Gardenville, Jamestown; and River City, in respective order, lie approximately in a straight line. The distance from Gardenville to Jamestown is 76 miles. The distance from Gardenville to River City is 159 miles. Find the distance from Jamestown to River City.

Answer 1

The distance between Jamestown and River City is 83 miles.

Explanation:

The three cities are positioned in a line, therefore by drawing a straight line from Gardenville to River City it should pass through Jamestown and have a length of 159 miles. This line will have two parts, the one that goes from Gardenville to Jamestown, which has a length of 76 miles and the one that goes from Jamestown to River city, which length we wish to know. This is illustrated in the annexed image. In order to calculate this distance we need to subtract the distance between Gardenville to River City and the distance between Gardenville to Jamestown.

`x = 159 - 76 = 83 \text{ miles}`
