Two rivers, A and B, flow together to form a larger river C. If the flux (volume rate of flow) of river A is 300 gallons per second and the flux of river B is 200 gallons per second, what is the flux of river C?

1)200g/s
2)250g/s
3)300g/s
4)500g/s

300

To find the flux of river C, we need to add the flux of river A and the flux of river B since they flow together to form river C.

Flux of river A = 300 gallons per second
Flux of river B = 200 gallons per second

Therefore, the flux of river C is the sum of the fluxes of rivers A and B:

Flux of river C = Flux of river A + Flux of river B
= 300 gallons per second + 200 gallons per second
= 500 gallons per second

Hence, the flux of river C is 500 gallons per second.

Therefore, the correct answer is option 4) 500g/s.
