Answer:
[tex] t = \frac{504.9m}{49.5 m/h}= 10.2[/tex]
And the best option would be:
10.2 h
Step-by-step explanation:
We have the following formula for the distance:
[tex] d = rt[/tex]
And we want to find the value of t with r = 49.5 m/h and d = 504.9 m. If we solve from t we got:
[tex] t = \frac{d}{r}[/tex]
And replacing the info given we got:
[tex] t = \frac{504.9m}{49.5 m/h}= 10.2[/tex]
And the best option would be:
10.2 h
