Question

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

Answer 1

Answer:

20 m/s

Step-by-step explanation:

speed of current is =2.5 km/h

man's speed with current =15 km/h

let the speed of man is =v

(v-2.5)=15

v=17.5

speed of man against current is

v-(-2.5)=17.5-(-2.5)

=17.5+2.5

=20
