Question

A 5m 60cm high vertical pole casts a shadow 3m 20cm long. Find at the same time (ii) the height of the pole which cast the shadow of 5m long.​

Answer 1

Step-by-step explanation:

Direct proportion

vertical pole = 5m 60cm = 560cm , other pole = ?

first shadow = 3m 20cm = 320cm

second shadow = 5m = 500cm

320 x other pole = 560 x 500

other pole = 560 x 500 / 320

other pole = 875cm = 8m 60cm
