Answers
Given : 80 कि.मी. दर ताशी या गतीने धावणाऱ्या आगगाडीने एका मालगाडीनंतर 6 तासांनी एक रेल्वे स्टेशन सोडले आणि 4 तासांनी तिला मागे टाकले.
A train running at a speed of 80 km / h , leaves after 6 hr of freight train and leaves behind freight train after 4 hrs
To Find : मालगाडीचा वेग किती आहे?
what is the speed of the freight train
(A) 32 कि.मी. दर ताशी
(B) 48 कि.मी. दर ताशी
(C) 60 कि.मी. दर ताशी
(D) 50 कि.मी. दर ताशी
Solution:
मालगाडीचा वेग = X कि.मी. दर ताशी
freight train speed = X km /hr
Travel time of freight Train = 6 + 4 = 10 hrs
Distance = Speed x Time
=> Distance = 10X km
train speed = 80 km /hr
Time = 4 hr
Distance = 80 x 4 = 320 km
10X = 320
=> X = 32
मालगाडीचा वेग 32 कि.मी. दर ताशी
Freight Train Speed = 32 km/hr
