Knowlesga Check Question 3 Two trains leave stations 532 miles apart at the same time and travel toward each other. One train travels at 105 iniles per hour while the other travels at 85 miles per hour. How long will it take for the two trains to meet? Do not do any rounding.

Which of the following is equivalent to \( \log \left(\frac{1}{x y}\right) \) ? (1 point) \( 1-\log x-\log y \) \( \log x-\log y \) \( -\log x-\log y \) \( -\log x+\log y \)

Simplify the logarithmic expression: \( \text{\log}_{2}(8) + \text{\log}_{2}(4) \)

Which of the following shows the equation \( 6^{2}=36 \) written in logarithmic form? (1 point) \( \log _{6} 36=2 \) \( \log _{2} 36=6 \) \( \log _{2} 6=36 \) \( \log _{36} 2=6 \)

Use logarithms to solve the equation for \( t \). R \( e^{0.27}=8 \)

Julie swam, biked, and ran in a 22.2 mile triathlon. She completed the race in 2.15 hours. The function \( m=13.8 \mathrm{~h} \) represents the miles \( m \) Julie biked in \( h \) hours. Was her average speed biking less than or greater than her average speed for the entire race? Justify your answer. Round to the nearest tenth if necessary.
