Given

On Thursday afternoon at camp, Elise played basketball and went swimming before dinner.She spent 1 hour and 30 minutes playing basketball and 1 hour and 35 minutes swimming.Dinner lasted for 1 hour and 10 minutes. If dinner ended at 7:10

SolutionWe need to start subtracting backwardStep 17 : 10p.m - 1: 10 = 6pmStep 26pm - 1:35= 4 : 25pmStep 34: 25 - 1 : 30 = 2: 55pmAlternatively(second method)Add all the time before dinner ended and then subtract from when dinner ended
`1\text{ :30 +1 : 35 +1 :10= 4 hours 15minutes}`

Now

`7:\text{ 10pm -4: 15= 2:55pm}`

The Final answer Elise started playing basketball at 2: 55pm
