SAT Question for April 20th

Difficulty:Medium

Category:Problem Solving and Data Analysis / Rates, Ratios, Proportions, and Percentages

Strategic Advice:Let the units in this question guide you to the solution. The speeds of the airplanes are given in miles per hour, but the question asks about the number of miles each airplane can travel in 12 seconds, so convert miles per hour to miles per second.

Getting to the Answer:

Slower airplane:

\frac{600 mi}{hr} \times \frac{1 hr}{60 min} \times \frac{1 min}{60 sec} \times 12 sec = 2 mi

Faster airplane:

\frac{720 mi}{hr} \times \frac{1 hr}{60 min} \times \frac{1 min}{60 sec} \times 12 sec = 2.4 mi

The faster plane can travel2.4 – 2 = 0.4miles farther, which is the same as $\frac{2}{5}$ miles.
