Question

Kendra set a goal to walk 10 miles in one week. She walked 2 miles on Monday and 3 miles on Tuesday. Which equation represents the number of miles, w, Kendra still needs to walk?

Answer 1

• w + 5 = 10
• 10 - 5 = w

Explanation:

Kendra has a goal to walk 10 miles in one week.

She has already walked 2 miles on Monday and 3 miles on Tuesday. This means that she has already walked:

= 2 + 3

= 5 miles

If she wants to walk a total of 10 miles with w being the remaining miles, the expressions will therefore be:

w + 5 = 10

or;

10 - 5 = w
