Answer:
[tex]Time = 250[/tex]
Step-by-step explanation:
Given
[tex]Length = 500yd[/tex]
[tex]Rate = 0.5sec/yd[/tex]
Required
Determine the time taken to reach the house
The given rate is a ratio of time to length.
i.e.
[tex]Rate = \frac{Time}{Length}[/tex]
Make Time the subject
[tex]Time = Rate * Length[/tex]
Substitute values for Rate and Length
[tex]Time = 0.5 * 500[/tex]
[tex]Time = 250[/tex]
Hence, the time taken is 250 seconds
