Budding college students across the country will be taking the ACT test on Saturday, December 10. To make sure you're on top of your game, The Princeton Review wants to challege you with some reading and science practice questions.
"Try the ACT practice questions* below to see if your algebra skills are up to par or if you still need some ACT math review," they say.
You are permitted to use a calculator for these questions. You may use your calculator for any problems you choose, but some of the problems may best be done without using a calculator.
1. Pierre competes in a triathlon, along a course as shown in the figure below. He begins swimming at starting point S and swims straight across the lake, gets on his bicycle at station A , bikes to station B , and then runs to finishing line F . The judges use a stopwatch to record his elapsed times of t A , t B , and t F , respectively. If the distance, in miles, between points S and A along the racecourse is denoted by SA , then what is Pierre's average speed for this race, in miles per hour?
