PLEASE HELP ME SOLVE !!!!

InMay 1998, forest fires in southernMexico

and Guatemala spread smoke all the way to

Austin. Those fires consumed forest land at a

rate of 26900 acres/week.

On the average, how many square meters

of forest are burned down every minute? An

acre is an area equivalent to that of a rectangle

60.5 yd wide and 80 yd long, there are 36

inches in one yard, and there are 2.54 cm in

one inch.

Answer in units of m2/min

Convert 26,900 acres/week to

_____ m^2/minute

1 acre = 4840 yard^2 (from the information given).

Multiply that by 9 ft^2/yd^2,and you get

= 43,560 ft^2 x 144 in^2/ft^2

= 6,272,640 in^2 x (2.54)^2 cm^2/in^2

= 40,468,564 cm^2

= 4046.9 m^2

1 week = 10,080 minutes

[26,900 acres/week / 10,080 min/week] * 4046.9 m^2/acre = ______ m^2/min
