Question

At a given time of the day, the ratio of the height of an object to the length of its shadow is the same for all objects. If a 3 ft stick in the ground casts a shadow is 1.5ft, find the height of a tree that casts a shadow that is 10.15ft

Answer 1

20.3 ft

Explanation:

The object-shadow ratio for the stick= 3÷1.5=2:1

The object-shadow ratio is same for all objects.

Let height of the tree be x

2/1 = x/10.15

x=10.15 * 2=20.3
