প্রশ্ন: Two motorists drove their cars at a speed of 45 km per hour and 50 km per hour respectively. One car took 10 minutes longer than the other to travel a distance. Find the distance travelled.

Hints: ধরি, ভ্রমণকৃত অংশের দৈর্ঘ্য x km = x/45 - x/50 = 10/60

( 10x - 9x) /450 = 1/6

x = 450/6

x = 75

[ NOTE: সঠিক উত্তর 75 km ]
