The speed of stream is 3 km/hr
<em><u>Solution:</u></em>
Given that girl is swimming downstream
To find: Speed of stream
In still water she can swim at 2km/h and the river is flowing with her
Speed in still water = 2 km/hr
She covered a distance of 12km in 2h 24 min
Distance = 12 km
time taken = 2h 24 min = 
Therefore,


<em><u>If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:
</u></em>
Speed downstream = (u + v) km/hr
5 km/hr = 2 km/hr + v
v = 5 - 2
v = 3 km\hr
Thus speed of stream is 3 km/hr
Answer:
The New Deal was a series of programs and projects instituted during the Great Depression by President Franklin D. Roosevelt that aimed to restore prosperity to Americans. When Roosevelt took office in 1933, he acted swiftly to stabilize the economy and provide jobs and relief to those who were suffering.
