Answer 1

Given:

During a winter storm, the amount of snowfall was recorded in 5 different locations.

All measurements have been rounded to the nearest 1/2 inch.

To find:

1+2+21/2+31/2=?

Solution:

From given, the amount of snowfall was recorded in 5 different locations are:

1 inch, 2 inch, 21/2 inch, 31/2 inch.

We need to find:

1+2+21/2+31/2

= [ 1 × 2 + 2 × 2 + 21 + 31 ] / 2

= [ 2 + 4 + 21 + 31 ] / 2

= 58 / 2

= 29 inch
