Question

John travels $4.19$ miles by train, $6.456$ miles by bus, $11.2$ miles by car, and $0.231$ miles by walk. How many miles did John travel in total?

• A. $23mi$
• B. $22.077mi$
• C. $22.09mi$

Answer 1

The correct option is B $22.077mi$

Distance traveled by train $=4.19mi$
Distance traveled by bus $=6.456mi$
Distance traveled by car $=11.2mi$
Distance traveled by walk $=0.231mi$

Total distance traveled $=(4.19+6.456+11.2+0.231)mi$
Step 1: Align the decimal numbers according to their place values one below the other.

Step 2: Add each column of digits starting from the right.

If the sum of the digits of a column is more than $10$, regroup the numbers and add them.


Finally, place the decimal point in the sum vertically below the decimal points in the addition operation.

Hence, John traveled $22.077mi$ in total.
