eef the points thanks man
thanks
Step-by-step explanation:
Estimation :
20/0.05 = 400
let
r--------> Alvin's average paddling rate in km/hour
y -------> speed of the current
in km/hour
we know that
speed= distance/time
------> solve for distance
distance=speed*time
to Campsite against the current
speed=r-y-----> speed=(r-3)
time=8 hours
distance=(r-3)*8------> equation 2
From Campsite with the current
speed=r+y-----> speed=(r+3)
time=3 hours
distance=(r+3)*3------> equation 1
equate equation 1 and equation 2-----> because is the same distance
(r+3)*3=(r-3)*8----> 3r+9=8r-24----> 8r-3r=24+9-----> 5r=33----> r=6.6 km/hour
therefore
the answer is
Alvin's average paddling rate is 6.6 km/hour

Answer:
2:45
Step-by-step explanation:
the tiny hand on the clock represents the hour while the long hand on the clock represents the minute(s).
that being said, the tiny hand is between 2 and 3-we can eliminate c and d.
look at the minute hand. it is on 9, which means 45
we can cross out 3:45 as the hour hand is not between 3 and 4.
this leaves us with 2:45
hope this helps :)
