Question

The amount of water that evaporation from a lake in 1 day was about 70 acre feet . which amount is closest to the rate of evaporation per hour

Answer 1

Answer:

2.9167 acre-feet ≈ 3 acre-feet per hour

Step-by-step explanation:

Data provided:

The amount of evaporation from a lake in 1 day = 70 acre-feet

also,

1 day = 24 hours

Therefore,

the rate of evaporation per hour = $\frac{\textup{Amount of evaporation}}{\textup{Total time}}$

or

the rate of evaporation per hour = $\frac{\textup{70 acre-feet}}{\textup{24}}$

or

the rate of evaporation per hour = 2.9167 acre-feet ≈ 3 acre-feet

Hence,

The evaporation rate per hour is closest to 3 acre-feet per hour
