Question

Two yachts are 39 miles apart. As they travel towards each other, they pass each other after 20 minutes . Given one yacht travels 6 miles per hour faster than the other, find the speeds of both yachts.

Answer 1

See below

Explanation:

20 minutes = 1/3 hr

distance / rate = time

x = rate1 x+6 = rate2

39 mi / ( x + x+6 m/hr ) = 1/3 hr

39/(1/3) = 2 x + 6

x = 55.5 mi/hr x+6 = 61.5 mi/hr
