With the aid of the current, patrick can row a canoe 3 mi in 12 mins. aginst the current, he requires 18 min to row the same distance. how fast does patrick row in still water, and how fast is the current?

Rowing speed is 12.5  miles/hour

Current speed is 2.5 miles/hour

Step-by-step explanation:

Speed is distance divides by time,  we usually use miles per hour  

In this case Patrick can row a canoe 3 mi in 12 mins

The speed is the miles he travel divides the time.

We express time in hour,  so 12 min is  0.2 of an hour ( 12/60)

Speed=3 miles/0.2 hours=15 miles/hour with the aid of the current

Against the current, 3 miles in 18 minutes

Speed=3 miles/0.3 hours=10 miles/hour against the current

His rowing speed is the average = (15+10)/2 = 12.5  miles/hour

The current speed is the difference = 15 - 12.5 = 2.5 miles/hour

its c or d   take a lucky guess my dude
