Here, Total distance = 440 m.  Total number of rotation  = 200 Therefore, distance covered in 1 rotation = 440/200  = 2.2m. Let the radius of the wheel be 'r' m. We know,  Distance covered in 1 rotation= .....

By mid-point theorem, PQ // BC   and  PQ = 1/2 . BC So, ∡BCA = ∡QPA    [ corresponding angles.] i.e; ∡BCA = 30o. Again, PQ = 1/2 . BC or, BC = 2 x PQ = 2 x 2.6cm = .....

Solution: Here, we have given, △ABC ∼ △DEC So,taking ratio of corresponding sides we get, BC / CD = AB/ED = AC/CE  or,  BC/ CD = 5cm/10cm = x / 9cm Taking   5cm/10cm = x / 9cm, we get 5cm/10cm X .....
