Question 13
Town E and Town F were 240km apart. Jason left Town E at 9.00a.m traveling at an average speed of 60km/h. Karen left Town E some time later than Jason and overtook him at 11.00a.m. Karen’s traveling speed was 90km/h.
a) At what time did Karen leave Town E?
b) How long had Karen rested when Jason finally reached Town F?
**Editorial note for this self-study exercise:** Assume both travel along the same route toward F at the stated constant speeds, without stops before F; Karen rests at F immediately after arriving. Enter part (a) as HH:MM on a 24-hour clock, then part (b) as a number of minutes, separated by a semicolon, with no spaces in the answer.
