Question

A forester wants to estimate the height of a tree. He is 6 ft tall and cast a shadow of 4 ft. If the shadow of the tree is 60 ft, how tall is the tree?

Answer 1

Answer:

90 ft

Step-by-step explanation:

Given,

The 6 ft tall man casts 4 ft long shadow,

So, the ratio of the height of the man and its shadow = $\frac{6}{4}$ = $\frac{3}{2}$

Now, suppose the height of the tree that casts the shadow of 60 ft long is h ft,

So, the ratio of the height of tree and its shadow = $\frac{h}{60}$

At the same time,

$\frac{h}{60}=\frac{3}{2}$

$h=60\times\frac{3}{2}=30\times 3=90$

Hence, the height of the tree is 90 ft

Answer 2

Since 4 is only 2/3 of 6, then you need to divide 60 into 3rds.
1/3 of 60=20
60+20=80!
Hopefully this is correct, but i will go check real quick!
