A boat travels 10 miles per hour upstream and 16 miles per hour downstream. How fast is the current?
Answers
Answer: The speed of the current is 3 miles per hour.
Step-by-step explanation:
Let x = speed of boat , y= speed of current.
Given:
x-y=10 (Upstream) ...(i)
x+y= 16 (Downstream) ...(ii)
Adding (i) and (ii), we get
2x=26
⇒ x= 13
Put x=13 in (i), we get
13-y=10
⇒ y=13-10
⇒ y=3
Hence, the speed of the current is 3 miles per hour.
