Nora jogs several times a week and always keeps track of how much time she runs each time she goes out. one day she forgets to take her stopwatch with her and wonders if there is a way she can still have some idea of her time. As she passes a particular bank building, she remembers that it is 4.3 km from her house. she knows from her previous training that she has a consistent pace of 4.0 m/s. How long has nora been jogging when she reaches the bank?
