Answer:

Machine B

Step-by-step explanation:

Since, Machine A covers $\frac{5}{8}$ square feet in $\frac{1}{4}$ hours,

Rate at which the Machine A is covering = $\frac{\frac{5}{8}}{\frac{1}{4}}$

= $\frac{5}{8}\times \frac{4}{1}$

= 2.5 square feet per hour

Machine B covers $\frac{2}{3}$ square feet in $\frac{1}{5}$ hours,

Rate at which the Machine B is covering = $\frac{\frac{2}{3}}{\frac{1}{5}}$

= $\frac{2}{3}\times \frac{5}{1}$

= $\frac{10}{3}$

= 3.33 square feet per hour

Therefore, Rate of Machine B is greater.
