Subtract 2 hours, 20 minutes from 4 hours, 10 minutes.
Dmitrij [34]
To make it easier convert the times all into minutes. 

2 hours 20 minutes = 120 minutes + 20 minute = 140 minutes 
4 hours 10 minutes = 240 minutes + 10 minutes = 250 minutes 

Then subtract: 

250 minutes - 140 minutes = 110 minutes 

Convert back to hours/minutes: 

110 minute = 1 hour and 50 minutes
