What we know:
- Progress has been made to 4.75
- Rate of digging is 3/5 mph
- Depth must be at least 12 1/2
- We need to find the minimum amount of time the machine works
How to solve:
By setting up an algebraic equation, we can solve this.
Process:
- Set up equation 4.75 + 3/5x = 12 1/2
- Convert 19/4 + 3/5x = 12 1/2
95/20 + 12/20x = 250/20
12/20x= 155/20
- Isolate x via division /(12/20) /(12/20)
- +Simplify
x= 12 11/20
Solution: 12 ; 45
