Question

If a truck takes 3 1/4 hours,and it has gone a 1/5 of the way.How much longer will it take to complete trip

Answer 1

Let's begin by listing out the information given to us:

Total Time = 3 1/4 hours

Time travelled already = 1/5 of total time

`\begin{gathered} (1)/(5)\cdot3(1)/(4)=(1)/(5)\cdot(13)/(4)=\text{ }(13)/(20)\text{ hour } \\ \\ OR \\ \\ (13)/(20)\cdot60=39\text{ minutes} \end{gathered}`

How much longer will it take to complete trip is calculated by the difference between Total Time & Time travelled already

`\begin{gathered} 3(1)/(4)-(13)/(20)=(13)/(4)-(13)/(20)=\text{ }(52)/(20)=(13)/(5)=2(3)/(5)\text{ hours} \\ \\ OR \\ \\ (13)/(5)\cdot60=156\text{ minutes} \end{gathered}`
