Answer» AVERAGE SPEED=total distance/total time Let distance to STORE be K then, total time =(K/20)+(K/30)=K/12 and, total time =(2K) so average speed= 2K / (K/12) = 24kmph. Average speed=total distance/total time Let distance to store be K then, total time =(K/20)+(K/30)=K/12 and, total time =(2K) so average speed= 2K / (K/12) = 24kmph.

Answer»

AVERAGE SPEED=total distance/total time

Let distance to STORE be K

then, total time =(K/20)+(K/30)=K/12

and, total time =(2K)

so average speed= 2K / (K/12) = 24kmph.

Average speed=total distance/total time

Let distance to store be K

then, total time =(K/20)+(K/30)=K/12

and, total time =(2K)

so average speed= 2K / (K/12) = 24kmph.
