b) it increases the boiling point and increases the freezing point of the water.
c) it decreases the boiling point and lowers the freezing point of the water.
d) it increases the boiling point and lowers the freezing point of the water.

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

Ithink it takes sixty votes to approve a supreme court justice

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
