Megan started biking to the internet cafe traveling 9 mph, after some time the bike got a flat so Megan walked the rest of the way, traveling 7 mph. If the total trip to the internet cafe took 9 hours and it was 75 miles away, how long did Megan travel at each speed

Let the distance she covered on her bike =D
Distance she walked to the cafe                =75 - D

 

D/9 + [75 - D] / 7 =9, solve for D
D =54 miles - that she walked !!
