You can put this solution on YOUR website! total time in seconds:
t = 5 + (2 min * 60 sec/min) + (17 min * 60 sec/min) + 32
t = 5 + (120) + (1020) + 32
t = 1177 sec
---
total distance in meters:
d = 15 + (3 km * 1000 m/km)
d = 15 + (3000)
d = 3015 meters
---
s = d / t
---
s = 3015 / 1177 = 2.562 m/sec
