Helen rounded the distance between two stores to 3.77 miles.

Question

Which of the following could be the actual distance?
A.
3.778 miles
B.
3.762 miles
C.
3.773 miles
D.
3.775 miles

Answer 1

To determine which distances rounded to 3.77 miles, we need to consider the rounding rules. When rounding to two decimal places, if the third decimal place is 5 or more, the second decimal place should be increased by 1. If it is less than 5, the second decimal place remains the same.

So, 3.77 rounded means that the actual value must be between:

3.765 (if rounded down) and 3.775 (if rounded up).

Now we evaluate each option:

A. 3.778 miles - This would round to 3.78 (so it's too high). B. 3.762 miles - This rounds to 3.76 (too low). C. 3.773 miles - This rounds to 3.77 (within the acceptable range). D. 3.775 miles - This rounds to 3.78 (too high).

The only distance that would round to 3.77 is:

C. 3.773 miles.
