12+__+18+__+__=___

She biked about _____
miles.

Answer 1

The answer is 71 miles

Explanation:

According to the decimal rule, the Monday's 12.3 will be rounded off to 12,Tuesday 14.1 will be rounded off to 14, Wednesday 17.7 will be rounded off to 18 as .7 is greater than .5,Thursday 11.8 is rounded off to 12 and Friday to 15

To calculate how far she biked in all in five days we add all the distances she covered every day.So,

12 miles+14 miles+18 miles+12 miles+15 miles= 71 miles.

Answer 2

71 miles

The mileage of each day is,

• Monday = 12
• Tuesday = 14
• Wednesday = 18
• Thursday = 12
• Friday = 15

Then the total miles will be,

→ 12 + 14 + 18 + 12 + 15

→ 71 miles

Hence, she biked 71 miles.
