Insect is 1.75 m away from the foot of the lamp post
Step-by-step explanation:
Let say after moving m meter Distance of insect from top of lamp post = m meter
Distance of insect from foot of lamp post = 8 - m m
Height of Lamp post = 6 m
Distance of insect from top of lamp post = m m
Applying Pythagorean theorem
m² = 6² + (8 - m)²
=> m² = 36 + 64 + m² - 16m
=> 16 m = 100
=> m = 6.25 m
Insect Distance from foot of lamp = 8 - 6.25 = 1.75 m
