Answer:
2 metric tons in an hour.
Step-by-step explanation:
The best way to do this is to convert all the fractions to decimals. The problem starts out looking like this.
Formula
Rate = Tons removed / hours
Tons Removed = 1/4 metric ton
Time taken = 1/8 hour
[tex]\text{rate = }\frac{\frac{1}{4}} {\frac{1}{8}}[/tex]
Rather than doing it with fractions, it is much easier to do it with decimals
1/4 = 0.25
1/8 = 0.125
Now what you get is rate = 0.25 / 0.125 = 2
So 2 metric tons can be removed in an hour
