Vikas can cover a distance of [20(2/3)] km in [7(3/4)] hours on foot.

1.	Vikas can cover a distance of [20(2/3)] km in [7(3/4)] hours on foot. How many km per hour does he walk?
Answer» 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

Answer»

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
