Question

. A man walks from his home to a town 6 km away at 4 km per hour
and returns again to his home at 12 km per hour using a Tonga. What
is the man's average speed for the double journey?​

Answer 1

Answer:

6 kmph

Step-by-step explanation:

Average speed: total distance/total time

Here, we are not given time so,

• First half: 6/4= 1.5 hours
• Second half: 6/12= 0.5 hours

Total time= 1.5+0.5= 2hours

Now, find the average speed,

• Total distance= 6+6= 12
• Total time = 2 hours
• Average speed= 12/2= 6kmph
