Racing Seconds — Important Questions

Blinking eyes, Snapping fingers, Making a phone call, Switching on lights, Filling a glass with water

Activities that take seconds: Blinking eyes (less than 1 second), snapping fingers (1 second), switching lights (2-3 seconds), filling a glass (10-20 seconds). Making a phone call usually takes several minutes, not seconds.

7 minutes 30 seconds

To convert seconds to minutes and seconds: Divide by 60. 450 ÷ 60 = 7 remainder 30. So 450 seconds = 7 minutes 30 seconds. Check: 7 × 60 + 30 = 420 + 30 = 450 seconds.

1 minute = 60 seconds, 1 hour = 60 minutes, 1 hour = 3600 seconds, Half an hour = 30 minutes

Correct time relationships: 1 minute = 60 seconds (not 100), 1 hour = 60 minutes, 1 hour = 60 × 60 = 3600 seconds, half an hour = 30 minutes. These are fundamental time conversions to remember.

6 minutes

To find race duration: End time - Start time = 10:31 AM - 10:25 AM = 6 minutes. Since both times are in the same hour, simply subtract the minutes: 31 - 25 = 6 minutes.
