Fran swims at a speed of 2.1 ​km/h in still water. The Lazy River flows at a speed of 0.7 ​km/h. How long will it take Fran to swim 10 km​ upstream? What is​ Fran's speed while swimming​ upstream?

Fran's speed while swimming​ upstream = 1.4 km/h

Step-by-step explanation:

Given: Fran's swimming speed = 2.1 ​km/h

Speed of river = 0.7 km/h

The direction against the stream is called upstream.

Speed in Upstream = Fran's swimming speed - Speed of river

= 2.1-0.7  km/h

= 1.4 km/h

hence, Fran's speed while swimming​ upstream = 1.4 km/h

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
