Answer:
0.6 km/hr
Step-by-step explanation:
Speed downstream: 13/5= 2.6 km/hr
Speed upstream: 7/5= 1.4 km/hr
Therefore, Velocity of current is: 1/2 (2.6-1.4) km/hr = 1/2(1.2) km/hr
The savings is the amount taken off or 32% of 150
32% of 150 is 0.32 times 150=48
savings is $48
or you can do
150/100=x/32
cross multiply to get
x=48
so savings is $48
