The next stop on the road trip is the zoo.
Jacob goes to find his favorite animal, the giraffe.
Jacob wonders how tall the tallest giraffe at the zoo is.
If Jacob is 5 feet 6 inches and his shadow at the time is 3 feet long.
Then the height of the giraffe whose shadow is 5 feet 9 inches at the same time will be
Let x be the hieght of the giraffe. Then we have
The ratio will remain constant.
x / 5.75 = 5.5 / 3
x = 10.54
x = 10 feet 6.5 inches
