Answer:

Step-by-step explanation:

9 1/3 is 9.333333333 but you only need the 9.333. So you look at the 3 after the nine. 4 or below goes to the number lower and 5 or higher goes to the number higher. So in this case 9.3 the 3 is smaller than 4 so therefore the number is smaller so it stays nine.

Mike can plow a field in 12 hours and his brother Phil can plow it in 15 hours. How long will it take them to plow it if they us

Korvikt [17]

Answer:

6.66 hours, that is, 6 hours and 40 minutes.

Step-by-step explanation:

If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.

If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.

So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:

(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66

So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.
