You can put this solution on YOUR website! s = d/t
t = d/s
---
monday:
t = 14/40
t = 0.35 hours
---
tuesday:
t = 14/45
t = 0.311111111111 hours
---
time difference:
= 0.35 - 0.311111111111
= 0.03888888888 hours
= 0.03888888888 hours * (60 minutes/hour)
= 2.3333333333 minutes
= 2 minutes and (0.3333333333 minutes * 60 seconds/minute)
= 2 minutes and 20 seconds
