Answer:
Upstream 18mph Downstream 36 mph
Step-by-step explanation:
Upstream DATA:
distance = 180 miles ; time = 10 hrs ; rate = 180/10= 18 mph
-----
Downstream DATA:
distance = 180 miles ; time = 5 hrs ; rate = 180/5= 36 mph
------
Equation:
Upstream: b - c = 18 mph
Downstream: b + c = 36 mph
Now solve for "b"
solve for "c"
