Question

Rita traveled 1,250 miles inthe first 3 days of her trip. At thisrate, how long will it take her totravel 1,875 miles?

Answer 1

we can make a relation and use cross multiplication

if Rita traveled 1,250 miles is 3 days how much days take to travel 1,875 miles

so

`\begin{gathered} 1,250\longrightarrow3 \\ 1,875\longrightarrow x \end{gathered}`

where x is the number of days to 1,875miles

to solve we multiply 1,875 by 3 (so the diagonal numbers ) and divide between 1,250

then

`\begin{gathered} x=(1,875*3)/(1,250) \\ \\ x=(9)/(2)=4(1)/(2) \end{gathered}`

so she takes 4 and a half days
