Question

Dianna runs a race of 2 miles in 8 minutes at a steady speed. Each mile she runs beyond 2 miles, her speed slows 1 mile a minute. It would take her ____ minutes to run 5 miles. (Enter only the number.)

Answer 1

Okay: We know that 2 Miles takes her 8 minutes. Every mile after that we add a minute. Let’s put that into a sequence:

4,8,13,19,26

We add an extra minute every mile after 8 minutes. +5,+6,+7

26 is your answer.

I hope this helps!
