D) 2.213 x 104 miles

Answer 1

Answer:

The total distance that Maria traveled is $2.213 \times 10^4$ miles.

Step-by-step explanation:

Given : Distance between Mexico City to Singapore = $1.26 \times 10^4 miles.$

Distance between Singapore to New York = $9.53 \times 10^3 miles.$

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

Solution;

Distance traveled by Maria from  Mexico City to Singapore =$1.26 \times 10^4 miles.$

Distance traveled by Maria from Singapore to New York =$9.53 \times 10^3 miles.$

So, Total distance traveled = $1.26 \times 10^4 +9.53 \times 10^3$

                                            =$12600+9530$

                                            =$22130$

                                            =$2.213 \times 10^4$

Hence the total distance that Maria traveled is $2.213 \times 10^4$ miles.

So, Option D is true .
