Question

A road is 120km long.There are poles on both sides of it starting from the beginni g to the end at an equal interval of 40m.How many poles are there in all?​

Answer 1

Answer:

3000 poles

Step-by-step explanation:

120 km =120000 m

No. of poles= Total distance/Distance between two poles

=120000/40

=3000 poles

Answer 2

Answer:

6000 poles

Step-by-step explanation:

no. of poles on both sides =2

total distance=120km=120000m

interval between 2 poles=40m

total no of poles =

$\frac{120000}{40} \times 2 = 6000$
