Answer:
d = (5√53)t
Step-by-step explanation:
After 1 hour, A is 10 miles north of the port, and B is 35 miles east of the port. Since these directions are at right angles, the Pythagorean theorem can be used to find the distance between the ships:
d = √(10² +35²) = √(100 +1225) = √1325 = 5√53 . . . . miles
The distance between the ships is increasing this number of miles each hour, so the desired expression is ...
d = (5√53)t ≈ 36.4t
