Answer:
1 hour and 53 minutes
Explanation:
You just need to subtract the times form each other.
There are two ways to do this.
Subtract the number of minutes and convert into total hours and remainder minutes.
Or you can just do the simple way shown by the answer above.
I will show the subtracting minutes one since it can be a base for all .
First we find how many minutes are in 7 hours and 10 minutes, and nine hours and three minutes.
7 hours and ten minutes is 430 minutes. 9 hours and 3 minutes is 543 minutes.
543 - 430 is 113.
Then you divide, we are using the remainder type division.
113/60(60 minutes in one hour)
60 goes into 113 one time and leaves 53.
Therefore, it takes 1 hour and 53 minutes.
