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
4+2i because you can’t have a negative square root
Answer:
4 * (x-9)=-30
not sure if u want it solved but if u do its x=6/4
Step-by-step explanation:
-5 1/3, -2 1/2, 3.75, 4.2 ( this is the order from least to greatest)
