Question 1046672: Landon started biking to the bookstore traveling 9 mph, after some time the bike got a flat so Landon walked the rest of the way, traveling 3 mph. If the total trip to the bookstore took 11 hours and it was 69 miles away, how long did Landon travel at each speed?

x=hours on the bike
11-x=hours walking
9x+3(11-x)=69. The speed times the number of hours equals the distance.
9x+33-3x=69
6x=36
x=6 hours on the bike and 5 hours walking. ANSWER
That is 6*9=54 miles + 5*3=15 miles, and that sum is 69 miles
