On a treadmill, Andrea walks a distance of 2 km. She then doubles the speed of the treadmill and jogs for another 2 km. If the total time she spent on the treadmill is 1 hour, find the speeds at which she walks and jogs.
Answered by Matt
a total of 4 km in one hr.
if she did at the same rate that would be 4 kph

Time=distance/walk speed + distance/run speed (ie. walk * 2)

T(x)=D/X + D/X*2
