alleryएक जहाज 90° के दिक्मान (bearing) पर 40 km चलता है, फिर 0° के दिक्मान पर 30 km चलता है। वह प्रारंभिक बिंदु से कितनी दूरी पर है?
A70 km
B10 km
C50 km
D35 km
Answer & Solution
Correct answer: C. 50 km
90° का दिक्मान पूर्व दिशा है और 0° का दिक्मान उत्तर दिशा है, इसलिए दूरी 1600 और 900 के योग का वर्गमूल है, जो 50 km है।
