Question

The shortest distance from the East Coast to the West Coast in the USA is 2,092 miles. The whole length of the Colorado River is about what percent of the distance from the East to the West Coast? Round your answer to the nearest whole percent.

Answer 1

The whole length of the Colorado River is about 69% of the distance

from the East to the West Coast

Explanation:

* Lets explain how to solve the problem

- The shortest distance from the East Coast to the West Coast in the

USA is 2,092 miles

- The length of the Colorado River is 2334 km

- We need to find the percentage of the whole length of the Colorado

River of the East to the West Coast

- The length of the Colorado River in kilometer and the distance from

the East Coast to the West Coast in miles then we must to change

the kilometers to miles

∵ The length of the Colorado River = 2334 km

∵ 1 km ≅ 0.6214 mile

∴ 2334 km = 2334 × 0.6214 = 1450.35 miles

∴ The length of the Colorado River is 1450.35 miles

- The percentage of one number from another number is the number

divided by other number and multiply the quotient by 100

∵ The distance from the East to the West Coast = 2092 miles

∵ The length of the Colorado River = 1450.35 miles

∵ % Colorado River =
`(1450.35)/(2092)*100=69.33`

* The whole length of the Colorado River is about 69% of the

distance from the East to the West Coast
