Answer 1

Answer:

Length of shadow of boy = 160 cm = 1.6 m

Step-by-step explanation:

Lamp height  = 3.3 m = 330 cm

Boy length = 110 cm

boy speed = 0.8 m/s  = 80 cm/sec

Distance covered in 4 secs  = 80 * 4 = 320 cm

let say shadow length = d cm

=>  110/d  = 330/(320 + d)

=> 320 + d = 3d

=> 2d = 320

=> d = 160

Length of shadow of boy = 160 cm = 1.6 m
