Question:

Tom and Jerry started jogging from the same start point of a 4 km track round a park. They started at the same time but in opposite directions. Both of them did not change their speed throughout. Jerry jogged at a slower speed than Tom. After 20 min, Tom jogged 3200 m. Jerry was 2000 m away from him. What was Jerry’s jogging speed in m/min?
