Question
It took less than 450 seconds for the child to travel from the first signpost to the second signpost.
Answer:
Yes, the child took less than 450 seconds for the child to travel from the first signpost to the second signpost
Explanation:
[tex]Speed=\frac {125}{60}=2.083333333 m/s\approx 2.083 m/s[/tex]
Distance=speed* time
Distance=2.083*450=937.5 m=0.9375 Km
For the child to travel 800 m, it required only [tex]\frac {800}{2.083}=384 seconds[/tex]
Therefore, it's proper to conclude that it took less than 450 seconds for the child to travel from the first signpost to the second signpost.
