Answers
Hawai jahaj ki mul chaal = 26.5 kilometre prati ghanta
Step-by-step explanation:
Hawai jahaj ki mul chaal = S kilometre prati ghanta
Duri = 15 km
samay = 15/S ghanta
chaal mein 200 kilometre prati ghanta vriddhi
Chaal = S + 200 kilometre prati ghanta
samay = 15/(S + 200) ghanta
30 minut = 30/60 = 1/2 ghanta
15/(S + 200) = 15/S - 1/2
=> 30S = 30(S + 200) - S(S + 200)
=> 30S = 30S + 6000 - S² - 200S
=> S² + 200S - 6000 = 0
=> S ≈ 26.5
Hawai jahaj ki mul chaal = 26.5 kilometre prati ghanta
