If you would like to know what is the speed in square inches per hour, you can calculate this using the following steps:
2880 square inches ... 1 1/2 hours = 3/2 hours
x square inches = ? ... 1 hour
2880 1 = 3/2 x
2880 = 3/2 x /2/3
x = 2880 * 2/3
x = 1920 square inches per hour
The correct answer would be 1920 square inches per hour.
