Answer:
a)27-x
b)27+x
Step-by-step explanation:
when a boat travels in the same direction as the current is downstream-->speeds the boat. If the rate of the boat in still water is 27 mph and the rate of the current of a river is x mph, the rate of the boat when the boat is going downstream is 27+x
when a boat travels against the current is upstream-->slow down. If the rate of the boat in still water is 27 mph and the rate of the current of a river is x mph, the rate of the boat when the boat is going upstream is 27-x
To find is out put it like this 2 8
5 x
you multiple so 2 times what eduals 8 then you take that and multiply by 5

$2.19 less if he paid separately
