A water and laser light show started at 19:45 hours and ended at 20:10 hours. For how long did the show last?

Hint:
It is given that a water and laser light show started at 19:45 hours and ended at 20:10 hours.
We have to find out how long the show lasts.
To find how long did the show last, we will subtract the two times given in the question.

Complete step by step solution:
It is given that a water and laser light show started at 19:45 hours and ended at 20:10 hours.
We have to find that how many long did the show last
Now,
Total time of show = $20:10 - 19:45$
 =$0:25$
=0 hour 25 minutes

$\therefore $ The show lasts for 25 minutes.

Note:
Conversion of hour into minute: To convert hours into minute we have to multiply with 60.
For example:
Let X be the number of hours and Y be the number of minutes.
Suppose X = 3hours then X in minutes = $3 \times 60 = 180$ and Y = 59 then total number of minutes is $180 + 59 = 239$ minutes.
