Answer:
hours
Step-by-step explanation:
Whenever 2 quantities (suppose a and b) are inversely proportional to each other, we can write an proportionality equation (with k as proportional constant) as:
![a=\frac{k}{b}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bk%7D%7Bb%7D)
Since, here t is INVERSELY PROPORTIONAL to r, we can say:
![t=\frac{k}{r}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bk%7D%7Br%7D)
Firstly, we have t = 2 hour and r = 40 mph, so we find k:
![t=\frac{k}{r}\\2=\frac{k}{40}\\k=2*40\\k=80](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bk%7D%7Br%7D%5C%5C2%3D%5Cfrac%7Bk%7D%7B40%7D%5C%5Ck%3D2%2A40%5C%5Ck%3D80)
Now, secondly, we have r = 45 and k = 80, we need to find t:
![t=\frac{80}{45}\\t=\frac{16}{9}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B80%7D%7B45%7D%5C%5Ct%3D%5Cfrac%7B16%7D%7B9%7D)
So, it would take
