in the 24-hour clock format is 09:58Ĥ:15 p.m.
Method 1: Convert the times to 24-hour clock format.ĩ:58 a.m. Simy practiced for 2 hours and 25 minutes.Ĥ. Since both times are in p.m., we can either convert the times to 24-hour clock format or directly subtract them. Solution: To find the duration of practice, we must subtract time. Simmy started practicing piano at 3:30 p.m. Hence, the subtraction will result in 3 hr and 35 min.ģ. Solved ExamplesĪfter subtracting the times, 4:10 and 1:05, we will get the time 3 hr and 5 min. There is a lot to learn about time subtraction, and SplashLearn is here to make this learning journey easier for you. Similarly, we can also add two times for any number of purposes.
