Answer:
2.96 h
Explanation:
We are given that
Speed of man,v=65mi/h
Time ,t=9.9 h
Total distance,s=451 miles
We have to find the time which you can spend over dinner and still arrive juts in time for the meeting.
Distance,[tex]d=v\times t[/tex]
Using the formula
[tex]d=65\times 9.9=643.5 miles [/tex]
Difference between distance=643.5-451=192.5 miles
Time,=[tex]t'=\frac{difference\;in\;distance}{speed}[/tex]
[tex]t'=\frac{192.5}{65}=2.96 h[/tex]
Hence, you can spend maximum time over dinner=2.96 h
