Answer:it will lose 2 gallons of water in 5 hours.
Step-by-step explanation:
A leaking pond loses 20 gallons of water in 49 hours. This means that the number of gallons of water that the pond will leak in one hour would be
20/49 gallons per hour.
Therefore, the number of gallons of water that the pond will lose in 5 hours would be
20/49 × 5 = 2.0408 gallons
Rounding to one decimal place, it becomes 2 gallons
Water lost in [tex]5[/tex] hours is equal to [tex]2.0[/tex] gallons.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Water lost in [tex]49[/tex] hours [tex]=20[/tex] gallons
Water lost in [tex]1[/tex] hour [tex]=\frac{20}{49}[/tex] gallons
So,
Water lost in [tex]5[/tex] hours [tex]=\frac{20}{49}\times 5[/tex]
[tex]=2.0[/tex] gallons
