I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)
First I did what’s inside the parentheses, (6x2) and got 12.
Then I divided 16 by 22 and received 0.72.
I added 0.72 with 12 and the result was 12.72.
Last step was to subtract 12.72 - 8 and that equals 4.72

Note that on a normal day, it takes him <span>1/3</span> hour to get to school. However, today it took <span><span><span>1/2 mile </span><span>2 mph</span></span>=1/4</span> hour to walk the first <span>1/2</span> mile. That means that he has <span>1/3−1/4=1/12</span> hours left to get to school, and <span>1/2</span> mile left to go. Therefore, his speed must be <span><span><span>1/2 mile</span><span>1/12 hour</span></span>=<span>6 mph</span></span>, so 6 is the answer.
