If he sold 61/10 pitchers (I made it into a improper fraction) on friday and he sold 1/4 on saturday, then you divide 61/10 by 4. when you do this you get 61/40 which simplifies 1 and 21/40 or 1.525 pitchers on saturday

Answer:
do you want us to answer all of them?
Step-by-step explanation:
Do you just want the answer or do you need the work too??
speed of current is 1.5 mi/hr
Answer:
let the rate in still water be x and rate of the current be y.
speed down the river is:
speed=distance/time
speed=14/2=7 mi/h
speed up the river is:
speed=(14)/(3.5)=4 mi/hr
thus total speed downstream and upstream will be:
x+y=7...i
x-y=4.......ii
adding the above equations i and ii we get:
2x=11
x=5.5 mi/hr
thus
y=5-5.5=1.5 mi/r
thus the speed in still waters is 5.5 mi/hr
speed of current is 1.5 mi/hr
