Answer

a. Vnorth = 625 km/h. Vwest = 553 km/h. b. Distance north = 1094 km. Distance west = 968 km

Work Step by Step

a. Vnorth = (835 km/h)(cos 41.5 deg) = 625 km/h. Vwest = (835 km/h)(sin 41.5 deg) = 553 km/h. b. Multiply the velocity components by a time of 1.75 hours to get 1094 km and 968 km, respectively.
