Hi Members,

This is the problem which I didn't understand.

Miss x walks 35km partly at the rateof 4km/hour and partly at 5km/hour;if she had walked at 5km/hour when she walked at 4km/hour and vice-versa,she would have covered 2 km more in the same time. Find the time she was walking.

Would any member explain me this problem and how to form simultaneous linear equations?
