El bote de Fran avanza a velo-
cidad de crucero de 20 mi/h en aguas quietas. Si recorre

la misma distancia en 3 horas a contracorriente que la que
recorrería en 2 horas con la corriente a favor, ¿cuál es la
velocidad de la corriente?

Respuesta :

Martebi

Based on the scenario above, Therefore, the speed of going against the current is 8.5.

What is the distance about?

Hours used  If one is going against the current = 3 hours

Hours used if one is going with the current = 2 hours

Therefore:

For speed as one is going against the current:

l + r =20

l -  r =3

2x = 23

x = 23/2

x= 11.5

11.5. +y = 20

y= 20-11.5

y = 8.5

Therefore, the speed of going against the current is 8.5.
