Jada is planning a kayak trip. She finds an expression for the time, T\left(s\right),T(s), in hours it takes her to paddle 10 kilometers upstream in terms of s,s, the speed of the current in kilometers per hour. This is the graph Jada gets if she allows ss to take on any value between 0 and 7.5 a. What would be a more appropriate domain for Jada to use instead?b. What is the approximate speed of the current if her trip takes 6 hours?

According to the given graph, the domain includes the values that Jada stated except for one of them, 5.5. As shown in the graph, there is one vertical asymptote at x=5.5. It means that the domain does not include this value.

Using this information we can write a new, more appropiate domain for Jada:

[tex]\lbrack0,5.5)\cup(5.5,7.5\rbrack[/tex]
