PLS HELP ME ASAP (SHOW WORK PLS) + LOTS OF POINTS (give thanks if correct)

Answer 1

It takes Layla $\frac{2}{5}$ hour to swim $\frac{1}{2}$ a mile. So, in order to find the time it would take to swim a full hour, you would have to multiply $\frac{2}{5}$ by the reciprocal, which is $\frac{5}{2}$. Then, you would multiply $\frac{5}{2}$ to $\frac{1}{2}$, which gives you $\frac{5}{4}$. So the answer is C, because $\frac{5}{4}$ is equal to 1$\frac{1}{4}$. Hope that helped!

Answer 2

It's  C because you change 2/5 into 4/10 then you add 4/10+4/10 which equals 8/10 and is 1 mph. So you add another 2/10 which is an half of a half which equals 1/4. So C
