Word problem using fractions for 5th grade

Question

A team practices at least 2 times/week for 5 weeks. Each practice is 45 minutes. Coach used table below to record number of practices and amount of time practiced each week:

 

Week/ # of Practices/ Time
1 / 3  / 1 ½ hours
2 / 2 / 2 ¼ hours
3 / 3 / 1 ½ hours
4 / 4 / 3 hours
5 / ? / ?

 

How many practices must the team have in Week 5 to have a total of 102 hours of practice for all 5 weeks?

 

Answer 1

Taking the problem at face value, the team has had 8.25 hours of practice so far.

 

102 - 8.25 = 93.75 hours that the team must practice in week 5.  If each practice is 0.75 hours (45 minutes), then:

 

Number of Practices = 93.75/0.75 = 125, or 25 practices a day assuming  a 5 day week.

 

Good luck getting the parents to agree to that!  ;-)

I'm guessing that the real number is 10.2 hours vice 102.  In that case:

 

10.2 - 8.25 = 1.95 hours of practice needed in week 5

 

Number of Practices = 1.95/0.75 = 2.6

 

But what is a fractional practice?  Who knows?  Were you able to get clarification from the teacher?
