Jun Li jogged for (2 + 5/6) km.

Kumar jogged (1+ 1/3) km more than Jun Lim

Firstly, make these mixed fractions into improper fractions:

2 + 5/6 = 12/6 + 5/6 = 17/6 km.

So Jun Li jogged for 17/6 km.

1 + 1/3 = 3/3 + 1/3 = 4/3 km.

Kumar jogged for (17/6 + 4/3) km = (17/6 + 8/6) km = 25/6 km. When adding the fractions use a common denominator.

Hence, together they jogged (17/6 + 25/6) km = (42/6) km = 7 km.
