Sophie has two new fish. She feeds one fish
4 pellets and the other fish 5 pellets each day. If Sophie
has fed her fish 72 pellets, for how many days has she
had her fish? Explain.

Step-by-step explanation:

One fish eats = 4 pellets

Second fish eats = 5 pellets

No of days one fish stays with Sophie = 72 ÷ 4 = 18 days

No of days second fish stays with Sophie = 72 ÷ 5 = 14.4 days

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
