Could use some help. I don't get this:
The maintenance department of a botanical garden is monitoring the displacement of statues that have moved by the process of creep. The statues must be straightened when the displacement reaches 15cm to prevent toppling. By measuring the tilt angle on the statues, they determined the creep rate in 2005 to be as shown in the table:
Date Installed...Rate (mm/yr)
1933.............2.01
1957.............2.35
1963.............3.1
1976.............2.69
1985.............2.5
Which statue will need to be straightened first?
