Question

A man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is:

Answer 1

The speed of man against the current is of

Vh = 12.5km / h

Step by step explanation:

      If the speed of a man in the currents is 15km / h and the speed of that current is 2.5km / h, then the man and the current have a relative speed

Vh / c = Vc + Vh

Where:

• Vh / c = 15km / h
• Vc = 2.5 km / h          Clear "Vh"

Vh = Vh / c - Vc             We replace

Vh = 15km / h - 2.5km / h

Vh = 12.5km / h

La velocidad del hombre contra la corriente es de

Vh = 12.5km/h

Explicación paso a paso:

      Si la velocidad de un hombre en la corrientes es de 15km/h y la velocidad de dicha corriente es de 2.5km/h, entonces el hombre y la corriente tiene una velocidad relativa

Vh/c = Vc + Vh

Donde:

• Vh/c = 15km/h
• Vc = 2.5 km/h    Despejamos "Vh"

Vh = Vh/c - Vc    Sustituimos

Vh = 15km/h - 2.5km/h

Vh = 12.5km/h
