Rohan is very intelligent in maths. He always try to relate the concept of maths in daily life. One day he is walking away from the base of a lamp post at a speed of 1 m/s. Lamp is 4.5 m above the ground.
(i) If after 2 second, length of shadow is 1 meter, what is the height of Rohan ?
(ii) What is the minimum time after which his shadow will become larger than his original height ?
What is the distance of Rohan from pole at this point ?
(iv) What will be the length of his shadow after 4 seconds ?

20:50 sir in question number 3 how the point will be the point where the hieght of Rohan is equal to shadow means in sample their is a choice between 2 or 3 if a person do so he thought they both are different and their isn't written?? May you tell about this ??

18:05 Sir in question number 2 can we do this?? We already give after 2 second his height became 1m if we put this on s=d/t so we get s=1/2 = 0.5m/second it means 1 second= 0.5m if we multiply both side with 3 so we get 3second = 1.5m is it right or wrong??

23:36 sir i also asked this in question 2 check it pls,in question 2 i found the shadow is increasing by 0.5m= 1 second so if we multiply with 4 so we get 2m=4second is it correct method or the marks will deduct??
