Two cruise ships leave port at the same time. Ship A sails north at a speed of 20 mph while Ship B sails east at a speed of 40 m

tiny-mole [99]

Answer:

a) D(t) = $20*\sqrt{5} * t$

b) 178.885 miles

Step-by-step explanation:

Ship A travels north at the rate of 20 mph.

Ship B travels east at the rate of 40 mph.

After t hours, Ship A is at a distance of 20t miles from the origin.

Similarly, Ship B is at a distance of 40t miles from the origin.

(a) Distance D(t) = $\sqrt{(20t)^{2}+(40t)^{2}}$

= $\sqrt{400*t^{2}+1600 * (t)^{2}}$

= $\sqrt{2000*t^{2}}$

= $20*\sqrt{5} * t$

(b) Distance between the two ships when t = 4,

= $20*\sqrt{5} * 4$

= $80*\sqrt{5}$ miles

= 80 * 2.236

= 178.885 miles
