Dog Walking Pace
Answer:
Walking the distance takes 17 minutes, which is 17 x 60 = 1020 seconds.
Walking 1.5 metres in every second, the distance walked is 1020 x 1.5 = 1530 metres.
The person walking the dog, also walks 1530 metres.
1 hour 20 minutes = 60 + 20 minutes = 80 minutes.
80 minutes = 80 x 60 seconds = 4800 seconds.
This person’s average speed
= 1530/4800 metres per second
= 0.31875 metres per second.
