Question

Tessie has a volleyball game at 6:45 p.m. she needs to be there 15 minutes early to warm up for the game and it takes her 40 minutes to go to The gym what time should she leave her house

Answer 1

First we need to add the time she takes warming and the time she takes going to the the gym:
$15minutes+40minutes=45minutes$

Next, we area going to subtract those 45 minutes from the time the game begins: 
$6:45pm-45minutes=6:00pm$

We can conclude that she should leaver her house at 6:00 pm if she wants to get in time for her 6:45 pm game.
