Question

A telephone company decided to put poles along the highway at every 600 meters, starting
with one at the beginning and one at the end. They measure and find that the highway is
3774 km long, and that they have only 4780 poles. How many additional poles will they
need?

Answer 1

3774000/600 meters = 6290

6290 - 4780 = 1510

Answer 2

Answer:

1510 additional poles are needed.

Step-by-step explanation:

1pole= 600 meters

? poles = 3774 km

convert 3774 km to meters = 3774000 meters

use ratio and proportion

3774000 ÷ 600 = 6290 poles

6290 poles are needed for 3774 km

total amount - amount that they have = additional poles needed

6290 - 4780 = 1510
