Mathematics for IGCSE & O level - Time (Section 2 - No. 6)
Carla set her digital recorder to start recording at 15:20 and to stop at 17:10. For how long was it recording?
1 hour 50 minutes
2 hours 10 minutes
1 hour 40 minutes
2 hours 50 minutes
Forklaring
Calculate the time difference. From 15:20 to 16:00 is 40 minutes. From 16:00 to 17:10 is 1 hour 10 minutes. So 40 minutes + 1 hour 10 minutes = 1 hour 50 minutes
