Gabriel can dig a 10 ft. by 10 ft. hole in ten hours. jessica can dig the same hole in eight hours. if they worked together how long would it take them?

4.44 repeating. Do you have to round it?

Step-by-step explanation:

(This is assuming the hole is somehow 2d? 10 by 10 means it has not width.)

1. 10×10=100

2. 100÷10=10

3. This means Gabriel Digs 10feet per hour.

4. 100 foot Hole. Jessica digs it in 8 hours. 100÷8=12.5

5. The combined rate at which they dig is 10+12.5 feet per hour, or 22.5 feet per hour.

6. 100÷22.5=4.4444 repeating.

i think the answer is b.

step-by-step explanation:

not 100% sure though.
