Detailed Solution
Download Solution PDFGiven:
Walking speed (initial) = 5 km/hr
Increased speed = 5 + 3 = 8 km/hr
Time difference = 6 hours
Formula used:
Distance = Speed × Time
Let the distance to be travelled = D km
Time taken at 5 km/hr = D / 5
Time taken at 8 km/hr = D / 8
Difference in time = 6 hours
So, (D / 5) - (D / 8) = 6
Calculation:
(D / 5) - (D / 8) = 6
⇒ (8D - 5D) / 40 = 6
⇒ 3D / 40 = 6
⇒ D = 6 × 40 / 3
⇒ D = 80
∴ The correct answer is option (1).
