Step 1
A person runs 5/2 miles and returnback by running 3/2 miles.
Total distance locked by them = 5 2 + 3 2 = 4   m i l e s
Step 2
A person runs 5 1 2 miles and on same path returns 3/2 miles. How far he is from its original point.
5 1 2 3 2
= 11 2 3 2 = 4   m i l e s
Step 3
A person runs at speed 3 1 2 km/h.
How much distance he will travel in 5/2 hr.
3 1 2 5 2 = 7 2 × 5 2 35 4 k m
Step 4
A person runs 8km in 3 1 2 hours.
What is his speed
speed=distance/time=\frac{8}{3\frac{1}{2}}=\frac{8}{7/2}=\frac{16}{7}km/hr.
