Detailed Solution
Download Solution PDFGiven:
Speed of train = 84 km/hr
Returns at the speed of 86 km/hr
Concept used:
\(Time = {Distance \over Speed}\)
Calculation:
⇒ \(T = {D \over S1} \;+\; {D \over S2}\;\;\)
⇒ \(170 = {D \over 84} \;+\; {D \over 86}\;\;\)
⇒ \(170 = {86D \;+\; 84D \over 7224}\;\)
⇒ 170 × 7224 = 170D
⇒ D = 7224
∴ The distance between Nadiad and Navsari is 7224 km.
