Question

"It takes 30 minutes to walk 2 miles. How long will it take to walk 7 miles? Use a double number line diagram to support your answer." Option 1: 70 minutes Option 2: 105 minutes Option 3: 120 minutes Option 4: 150 minutes

Answer 1

105 minutes (1 hour 45mins)

Explanation:

We know that is takes 30 minutes to walk 2 miles. To get the amount of time it takes to walk 1 mile divide 30 by 2> 30 divided by 2 equals 15. Then we know how long it takes to walk 1 mile so now all we need to do is figure out how long it takes to walk 7 miles. To do that we multiply 15 times 7. 15 times 7 gets you to 105. So the answer is 105 minutes or 1 hour and 45 minutes.
