this distance time graph represents a journey made by sue work out how much time she spends stationary.
The time she spends stationary will be represented by the length (in time) of the horizontal line segments on the graph
The first one is from 3 PM to 3:30PM = 30 min
The second one is from 4PM to 5PM = 1 hr
The third oneis from 6:30 PM to 7:30 PM = 1 hr
So....the time stationary = 2 hrs 30 min
