A boat trip travels are 15 miles in the direction of 45° east of north for an hour the boat then turn and travels at 18 m/s in a direction 5° north of East for an hour

Hello your question is incomplete below is the missing piece

What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.

answer :  25.73 m/s

Explanation:

Given

V1 = 15 miles/hour =  6.71 m/s [ 45° EN ]

V2 = 18 m/s [ 5° NE ]

Calculate  the resultant velocity

Vr = 6.71 m/s[45°] + 18m/s[5°].

Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )

Vr = ( 4.74  + 4.74 i  )+  ( 17.93 + 1.57i) = 22.67 + 12.18i.

Therefore the magnitude

= = 25.73 m/s

the answer is to check all of them! they all apply well at least i think so!
