B) 1.079 x 103 miles

C) 1.079 x 107 miles

D) 2.213 x 104 miles

Answer 1

The total distance that Maria traveled is
`2.213 * 10^4` miles.

Explanation:

Given : Distance between Mexico City to Singapore =
`1.26  * 10^4 miles.`

Distance between Singapore to New York =
`9.53 * 10^3 miles.`

To Find : What is the total distance that Maria traveled?

Solution;

Distance traveled by Maria from Mexico City to Singapore =
`1.26  * 10^4 miles.`

Distance traveled by Maria from Singapore to New York =
`9.53 * 10^3 miles.`

So, Total distance traveled =
`1.26  * 10^4 +9.53 * 10^3`

=
`12600+9530`

=
`22130`

=
`2.213 * 10^4`

Hence the total distance that Maria traveled is
`2.213 * 10^4` miles.

So, Option D is true .
