Question

a mile equals 63,360 inches. estimate the number of inches in 5 miles by rounding 63,360 to the nearest ten thousand

Answer 1

Rounding 63,360 to the nearest ten thousand = 60,000

1 mile = 60,000 inches

5 miles = 5 x 60,000 = 300,000 inches

Answer

300,000 inches

Answer 2

Hi!

First, round 63,360

• The number in the 10 thousands place is 63,360

• Look to the right of the 6, is the number less than or greater than or equal to 5?

• It is less than 5, so we round down.

60,000

Multiply by 5

60,000 × 5 = 300,000

There are about 300,000 inches in 5 miles.

Hope this helps! :)
