Answer :
Answer: 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.
