Rohan is very intelligent in maths.

He always tries to relate the concept of maths to daily life.

One day he is walking away from the base of a lamp post at a speed of 1 m/s.

The lamp is 4.5 m above the ground.

If after 2 seconds, the length of the shadow is 1 meter.

Then the height of Rohan will be

Speed = 1 m/s

Distance covered in 2 secs = 2 m

The length of the shadow is 1 meter,

Total Distance from base = 2 +  1  = 3 m

Then the height of the Rohan will be

                     1/3  = Height of rohan / 4.5

Height of Rohan = 1.5 m

Height of Rohan = 150 cm
