A coast guard helicopter receives a distress signal from a boat. the units (15,80) (55,38)represent miles. to the nearest minute, how long will it take the helicopter to reach the boat if the helicopter travels at an average speed of 75 miles per hour?

• Algebra -

(15 , 80) , (55 , 38).

d^2 = (55 - 15)^2 + (38 - 80)^2,
d^2 = (40)^2 + (-42)^2,
d^2 = 1600 + 1764,
d^2 = 3364,
d = 58 Miles.

• Algebra -

t = 58 mi / 75 mi / h = 0.77 h = 46 min
