Question 7
Town A and Town B are 378km apart. At 9 : 45 a.m, Roy set off from Town B to Town A at an average speed of 88km/h. 15 minutes later, Sam set off from Town A to Town B at an average speed of 90km/h.
a) How far from Town A was Roy at 10a.m?
b) At what time did Sam and Roy pass at each other?
**Editorial note for this self-study exercise:** Assume both travel toward one another along the same route at the stated constant speeds, with no stops before meeting. Enter the distance in kilometers, then the meeting time as HH:MM on a 24-hour clock, separated by a semicolon with no spaces.
