Answer 1

Calculate the two pieces and you'll be done.

Answer 2

@tkhunny
I'm not sure how to do that....I'm really confused

Answer 3

Distance = Rate * Time

Put each circumstance in the formula. I'll do one.

11s at a speed of 1m/s

Distance = 1 m/s * 11 s = 11 m

Okay. Your turn. 11s at 3.2m/s

Answer 4

3.2m/s * 11 =35.2

Answer 5

Okay. It should be "m", but that's good.

Now, add up the total time and the total distance. You'll be done.
