Can you answer this math question from a practice test for the SAT? [View all]

http://www.upworthy.com/can-you-answer-this-sample-question-from-the-newly-redesigned-sat

SAT study blogs recommend spending only about 75 seconds on each math problem, so you should set a timer.

Ready?

A typical image taken of the surface of Mars by a camera is 11.2 gigabits in size. A tracking station on Earth can receive data from the spacecraft at a data rate of 3 megabits per second for a maximum of 11 hours each day. If 1 gigabit equals 1,024 megabits, what is the maximum number of typical images that the tracking station could receive from the camera each day?

A) 3
B) 10
C) 56
D) 144

*You can find the answer at the bottom of this story.

Keep in mind that the numeric details here are presented in an intentionally confusing order, from which multiple equations must be extrapolated before any math can actually be done.

Give up? Timer run out? Or hey, maybe you answered it without even blinking (no judgements here ... nerd).
That question comes from the newly redesigned SAT, which will roll out in March 2016.
