The distance between the places H and O ...

The distance between the places H and O is D units. The average speed that gets a person from H to O in a stipulated time is S units. He takes 20 minutes more time than usual if he travels at 60 km/h, and reaches 44 minutes early if he travels 75 km/h. The sum of the numerical values of D and S is:
H और O स्थानों के बीच की दूरी D इकाई है। H से O तक जाने में एक निर्धारित समय में S इकाई की औसत चाल को प्राप्त करता है। यदि वह 60 किमी/घंटा की चाल से यात्रा करे, तो उसे सामान्य की तुलना में 20 मिनट अधिक समय लगेगा और वह यदि वह 75 किमी/घंटा की चाल से यात्रा करे, तो वह 44 मिनट पहले पहुँचेगा। D और S के संख्यात्मक मान का जोड़ है:
