GRE Math Practice: Plugging In for Quantitative Comparison Questions - Jan and Marko's Race

Assalamu Alaikum
Welcome to Doct Maths!
In this video, we solve two challenging GRE Math questions:
Question 7: Jan and Marko are competing in an off-road race. Jan completes 3/4 of the race in 2 hours. Marko completes 2/3 of the race in 5/8 of the time it takes Jan to complete 9/10 of the race. Who is faster? We break down the problem and calculate their speeds step-by-step.
Question 8: We compare two quantities:
• Quantity A: 3a5
• Quantity B: (3a)5
Using the plugging in technique, we determine which quantity is greater.
