Final answer:
For every 1 square mile that Bao mows, Xavier mows 4/5 of a square mile. The ratio of their mowing outputs is 4/5, which is choice B.
Step-by-step explanation:
The question asks for the comparison of areas mowed by Xavier in relation to Bao. Given that for every 1/150 square mile Xavier mows, Bao mows 1/120 square mile, we can set up a ratio to find out how much Xavier mows for every 1 square mile Bao mows:
- Xavier mows: 1/150 square mile
- Bao mows: 1/120 square mile
To find the equivalent for 1 square mile that Bao mows, we use the following ratio:
(1/150) / (1/120) = 120/150 = 4/5
Therefore, for every 1 square mile Bao mows, Xavier mows 4/5 of a square mile.
