u have to draw a tangent to the point (where the dent lies)
this way u get the point on the x-axis near 24
24-20 = 4 --> 4/2 = 2
2*12 = 24m!
hope this helped

if u see carefully...the curve touches the x-axis at 25..
but u dont have to take the curve...its the tangent to the curve
therefore the answer lies between 24<= ans <= 28

s= ut + 0.5a(t^2)
s = (u+v)/2
v = u + at
v^2 = u^2 + 2as

16.3 (heat from heater +heat from surrounding) - 2.1(heat from surrounding) = 14.2 (heat from hetaer)
is tht easier...
