From the question,
Distance covered by vikas in [7(3/4)] hours on foot = [20(2/3)] km = (62/3)
Distance covered by vikas in 1 hour = (62/3) ÷ (31/4)
Then we have,
= (62/3) × (4/31)
(Because reciprocal of (31/4) is (4/31)
= (62 × 4) / (3 × 31)
= (2×4) / (3×1)
= (8) / (3)
= [2(2/3)] km
Hence, Distance covered by vikas in 1 hour is [2(2/3)] km
