Boat A leaves a dock headed due west at 5 00 PM traveling at

Boat A leaves a dock headed due west at 5: 00 PM traveling at a speed of 9 mi/hr. At the same time, Boat B leaves the same dock traveling due south at a speed of 21 mi/hr. Find an equation that represents the distance d in miles between the boats and any time t in hours. What would be the answer to this in miles?

Solution

distance travelled by boat A in t hours =9t miles

distance travelled by boat B in t hours =21t miles

distance between the boats ,d=[(9t)²+(21t)²]

distance between the boats ,d=[81t²+441t²]

distance between the boats ,d=[522t²]

distance between the boats ,d=(522)t miles

yes answer will be in miles
