Question

how many 60cm long rulers need to be placed end to end to cover 1.5km?

Answer 1

1.5 Km = 1500 m

1 m = 100 cm

=> 1500 m = 1500 * 100 = 1,50,000 cm

So 1 Scale = 60 cm, then how many scales will equal to 1,50,000 cm

Product of means = Product of Extremes

1 * 1,50,000 = 60 * x

=> x = 1,50,000 / 60

=> x = 2500

Hence 2500 scales of 60 cm each is required to cover a distance of 1.5 km

Answer 2

Answer:

the answer is 2500

Step-by-step explanation:

1.5km= 1500

60cm=0.6

1500 divided by 0.6=2500
