TJ Prep Problems

TJ test prep practice problems  for our students and readers. The problems provide a very small sampling of what Optimal TJ Prep students work with.

An Algebra Problem for TJ/AOS/Blair/ACT/SAT Prep (Easy). Target Time. 15-40 seconds.

Maya bikes for 24 minutes at 24 MPH. At what speed she must bike for the next 6 minutes so that her average speed for the entire trip will be 20 MPH?

Note. If you can't solve this problem within 40 seconds, you do not completely understand speed-distance problems. If you can solve it but take more than 20-30 seconds then there is room for significant improvement in your problem solving skills.
