Question

migration many american white pelicans migrate each year, with hundreds of them stopping to rest in various locations along the way. the ratio of the distance some flocks travel from their summer home to one stopover to the distance from the stopover to the winter home is 3:4. if the total distance the pelicans migrate is 1680 miles, how long is the distance from the summer home to the stopover?
mi

Explanation:

Step1: Determine total parts of the ratio

The ratio of the distance from summer home to stopover (\(d_1\)) to stopover to winter home (\(d_2\)) is \(3:4\). So total parts \(= 3 + 4 = 7\) parts.

Step2: Find value of one part

Total migration distance is \(1680\) miles, which is \(7\) parts. So one part \(=\frac{1680}{7}=240\) miles.

Step3: Calculate distance from summer home to stopover

Distance \(d_1\) is \(3\) parts. So \(d_1 = 3\times240 = 720\) miles.

Answer:

\(720\)
