Question

The average speed of bond in the first,second & third km at 20,16,12 km/hr respectively in km/hr is

Answer 1

The average speed of bond is 15.32 km/hr

Explanation:

Since we know that

Average Speed = Total distance covered /Total time taken

Here total distance is 3 km

Now putting the values in the formula we get

       = 3/(1/20 + 1/16 + 1/12)

 = (3 x 20 x 16 x 12)/(192+240+230)

        =  15.32 km/hr

Hence the average speed of bond is 15.32 km/hr
