How can you use four rods that measure 2 cm 5 cm 7 cm 9 cm to measure a length of one
vichka [17]
<span>If you put the 9cm and 2cm rods together end-on-end, the new length is 11cm. Now if you repeat this with the 7cm and 5cm rods that new length is 12cm, so the difference between the two is now 1 cm. It does not seem very practical to walk around measuring items using the rods like this, so you could then make a small rod or use a strip of paper equal to the difference (1cm) as a standard measuring tool.</span>

Total time taken = (8 / x) + (21 / y) hours

Total time taken = (8 / x) + (21 / y) hours
