Question

Can someone help and explain​

Answer 1

Answer:

$\frac{1}{2}$ blocks

Step-by-step explanation:

If it takes 15 minutes to walk 7 1/2 blocks, it should be 15:17$\frac{1}{2}$

The left side is minutes and the right side is the number of blocks

15:17$\frac{1}{2}$

 1: ?  Since we are figuring out how many blocks he can walk in a minute, the left side is 1 and the right side is a question mark because we have not figured it out yet.

15: 17 $\frac{1}{2}$    Divide by 15 on both sides because that is the "distance" from 15 to1

 1 : ?

1: $\frac{1}{2}$

So the answer is $\frac{1}{2}$
