If a 20-foot tree casts a shadow of 15 ft how long is the shadow of a student who is 5 ft 4 in tall?

Answer:

4 feets

Step-by-step explanation:

Given that :

Height of tree = 20 feets

Shadow of tree = 15 ft

Height of student = 5ft 4 in ; 4 in = 0.3333 foot = 5.3333 feet

Shadow of student = s

Height of tree / shadow of tree = height of student / shadow of student

20 / 15 = 5.33333 / s

Cross multiply :

20 * s = 15 * 5.33333

s = 79.99995 / 20

s = 3.9999975

Shadow of student =, 4 feets
