QuestionAmerican White Pelicans migrate 1680 miles. If the ratio of summer home to stopover is 3:43:4, find the distance to the stopover in mi.

Studdy Solution

STEP 1

Assumptions1. The ratio of the distance from the summer home to the stopover to the distance from the stopover to the winter home is34. . The total distance that the pelicans migrate is1680 miles.

STEP 2

The total ratio is the sum of the individual ratios. In this case, it's (for the distance from the summer home to the stopover) plus4 (for the distance from the stopover to the winter home).
Totalratio=+4Total\, ratio = +4

STEP 3

Calculate the total ratio.
Totalratio=3+=7Total\, ratio =3 + =7

STEP 4

Now we can find the length of each part of the journey by dividing the total distance by the total ratio. This gives us the length of one "unit" of the journey.
Unitlength=Totaldistance/TotalratioUnit\, length = Total\, distance / Total\, ratio

STEP 5

Plug in the values for the total distance and the total ratio to calculate the unit length.
Unitlength=1680miles/7Unit\, length =1680\, miles /7

STEP 6

Calculate the unit length.
Unitlength=1680miles/=240milesUnit\, length =1680\, miles / =240\, miles

STEP 7

Now we can find the distance from the summer home to the stopover by multiplying the unit length by the ratio for this part of the journey.
Distancefromsummerhometostopover=UnitlengthtimesRatioforthispartDistance\, from\, summer\, home\, to\, stopover = Unit\, length \\times Ratio\, for\, this\, part

STEP 8

Plug in the values for the unit length and the ratio for this part of the journey to calculate the distance from the summer home to the stopover.
Distancefromsummerhometostopover=240milestimes3Distance\, from\, summer\, home\, to\, stopover =240\, miles \\times3

STEP 9

Calculate the distance from the summer home to the stopover.
Distancefromsummerhometostopover=240milestimes3=720milesDistance\, from\, summer\, home\, to\, stopover =240\, miles \\times3 =720\, milesThe distance from the summer home to the stopover is720 miles.
