A boat is traveling east across a river that is 112 meters wide at 8 meters per second. If the river has a northward current of 5 meters per second, what is the resultant speed of the motorboat rounded to the nearest tenth?

 

a) 8.6 m/s

 

b) 13.0 m/s

 

c) 3.0m/s

 

d) 9.4 m/s

sqrt  ( 8^2 +  5^2)  =  sqrt  ( 64  + 25)  = sqrt (89)  ≈  9.4  m/s
