This math skill teaches how to calculate elapsed time between two digital clock readings by separately determining the difference in minutes and hours, then combining them for a total elapsed time.
Elapsed time from digital clocks
Test your understanding of elapsed time from digital clocks by practicing it! Work through the below exercises to use it in practice.
🎙️
How much later is the second clock?
🎙️
First let's tell the time on both clocks. The first clock shows 9 o'clock, and the second clock shows 10 fifteen.
🎙️
Look at the minutes first The second clock is 15 minutes later.
🎙️
Now look at the hours. The second clock is 1hr later.
🎙️
So the second clock is 1 hour and 15 minutes later. Or, since an hour is 60 minutes, that's 75 minutes later.
