Detailed Solution
Download Solution PDFGiven:
Speed from Kandla to Mahesana = 82 km/hr
Speed from Mahesana to Kandla = 84 km/hr
Total time = 166 hours
Formula used:
Total time = Time for forward journey + Time for return journey
Time = Distance / Speed
Calculation:
Let the distance between Kandla and Mahesana be D km.
Total time = (Distance / Speed forward) + (Distance / Speed return)
⇒ 166 = (D / 82) + (D / 84)
⇒ 166 = (84D + 82D) / (82 × 84)
⇒ 166 = (166D) / (82 × 84)
⇒ D = (166 × 82 × 84) / 166
⇒ D = 82 × 84
⇒ D = 6888 km
∴ The correct answer is option (2).
