Scientists estimate forests are being destroyed on Earth's surface at a rate of 149 acres per minute. Use unit ratios to find the number of acres to the nearest thousand being destroyed each day.
I am completely stumped on this one. HELP!
Cross multiply and solve for x.
149 / 1 = x / 1,440
To find the number of acres being destroyed each day, we first need to convert the rate from acres per minute to acres per day.
There are 60 minutes in an hour, and 24 hours in a day. Therefore, there are 60 x 24 = 1440 minutes in a day.
To find the acres destroyed per day, we can set up a unit ratio based on the given rate:
149 acres/1 minute = x acres/1 day
To find x (the number of acres destroyed per day), we can cross-multiply and solve for x.
x = (149 acres/1 minute) * (1 day/1440 minutes)
x = (149/1440) acres/day
Finally, we can calculate the value of x:
x ≈ 0.1034 acres/day
Rounding this value to the nearest thousand, we have:
x ≈ 0.103 thousand acres/day
Therefore, the approximate number of acres being destroyed each day is 0.103 thousand acres, or about 103 acres.
