If a fish can swim short distances at 48km/h, how long would the fish take to reach a smaller fish that is 3m away?

48km=48000m
3/48000=1/16000 h
1h=3600 sec
(1/16000)*3600=3600/16000= 0.225 sec 
48 sec

first convert km to miles. km times 1.609
48 km is 29.83 miles rounded off.
So, 48km/hr is the same as 29.83mi/hr.
Divide 29.83 mi/hr by 60 to find mile per minute.
29.83¡À60 = .4971 which can be rounded of the .50 mile per minute.
That is ¨ö mile per minute. Small fish is 3 miles away. So divide distance by rate: 3¡À¨ö which becomes 3• 2/1 = 6 minutes.
The answer is 6 minutes.
