Answer:
its 2 hours
Step-by-step explanation:
first, you say, well it's 7 days in a week and it says they practice 25 minutes every night. So there for, you multiply, 25 times 7. and that gets you 175, now, it says how many hours does a band member practice weekly. and 60 minutes is in an hour so you have to divide, 60 divided by 175. which gives you 2 with the remainder of 55. But see don't forget it said about which means estimate or round up. so 2 with a remainder of 55, (if it's seven or up `round it up). meaning to the next number. Hopefully, this helped.
