The Labour Day "Men's Marathon" began at 8:45 a.m. Jack finished the marathon at 11:10 a.m.
(a) Calculate, in hours and minutes, the time taken to run the course.
8:45 - 10:45 = 2 hours
10:45 - 11:10 = 25 minutes
To calculate the time taken to run the course, we need to subtract the start time from the finish time.
Start time: 8:45 a.m.
Finish time: 11:10 a.m.
First, let's convert the start and finish times to a 24-hour format for easier calculation.
Start time in 24-hour format: 08:45
Finish time in 24-hour format: 11:10
Now, let's calculate the time difference between the two.
11:10 - 08:45 = 02:25
The time taken to run the course is 2 hours and 25 minutes.
