If Amanda can run the length of a football field 2000 meters in length in 2 hours, how long would it take her to run the length of a 10000-meter track at the same speed?
Running the length of a football field 2000 meters in 2 hours is a speed of 2000/2=<<2000/2=1000>>1000 meters per hour.
At the same speed, Amanda will run the length of a 10000-meter track in 10000/1000 = <<10000/1000=10>>10 hours
