Answer:

120 minutes

Step-by-step explanation:

large horse + small horse = together

1 pool/40 minutes + x = 1pool/30 minutes

1/40 + x = 1/30

subtract 1/40 from both sides

x = 1/30 - 1/40

use 120 as common denominator

x = 4/120 - 3/120

x = 1/120

x = 1 pool / 120 minutes

It takes the small horse 120 minutes
