Question 18 (5 points) The time T, it take Bob to biked to work varies inversely as his cadence R (Rate of pedaling in revolutions per minute) Give the general equation, us a lower case k for the constant of variation. If is cadence is 50 RPM's it take him 42 minutes to bike to work. Q/ U Find the constant of variation. Q/ D How long would it take him to bike to work if he increased his cadence to 75 RPMs? 13/ minutes D Question 19 (5 points) The air resistance an object encounters varies jointly as it's surface area and the square of it's velocity. A trailer with a surface area of 120 square feet and a velocity of 50 MPH has a wind resistance of 6300 Newtons. Find the constant of variation. Express as a decimal. Do not round! CH The surface area of the trailer is reduced to 80 square feet and the velocity is reduced to 45 MPH. What is the air resistance
