Answer 1

Answer:

What we have to find out...............

Answer 2

Case 1

Speed =8km/h

Let, distance be x km

Then, Speed = Distance

Time

8 = x

T

T = x km

8

Case 2

Speed = 12km/hr.

Let distance be x km

Then, Speed = Distance

Time

12 = x

T

T = x

12

Then,

x/8 + x/12 = 5

20x/96 = 5

x = 96×5

20

x = 24

Therefore, x = 24
