To find the total distance traveled by the man, we need to calculate the distance covered during the first half of the journey and the distance covered during the second half, and then sum them up.
First, let's calculate the distance covered during the first half of the journey.
Time taken to cover the first half = 5 hours + 15 minutes = 5.25 hours
Speed during the first half = 60 km/h
Distance covered during the first half = Speed × Time = 60 km/h × 5.25 hours = 315 km
Now, let's calculate the distance covered during the second half of the journey.
Time taken to cover the second half = Total time - Time taken for the first half = 5.25 hours - 5.25 hours = 0 hours
Since the time taken for the second half is 0 hours, the distance covered during the second half is also 0 km.
Finally, the total distance traveled by the man is the sum of the distances covered during the first and second halves:
Total distance = Distance covered during the first half + Distance covered during the second half = 315 km + 0 km = 315 km
Therefore, the man traveled a total distance of 315 kilometers.
