Question

Walter drove his truck 1,404 miles for a trip. He drove at an average speed of 52 miles per hour. Walter split the trip into 3 sections of equal time. How many hours did it take Walter to drive each of these 3 sections?

Answer 1

Since Walter split the trip into 3 sections of equal time, we can divide the total miles in three to get the following:

`(1404)/(3)=468`

Then Walter drove 468 miles in each section. Now, he drove at an average speed of 52 miles per hour, then:

`\begin{gathered} 52mi\rightarrow1h \\ 468mi\rightarrow x \\ \Rightarrow x=(468mi\cdot1h)/(52mi)=9h \\ x=9h \end{gathered}`

therefore, Walter drove for 9 hours in each section.
