Question

Traveling at 55 miles per hour how many minutes rounded to the nearest whole number does it take to drive 310 miles

Answer 1

so, it takes 1 hour, or 60 minutes, to travel 55 miles, how many minutes does it take for 310?


`\bf \begin{array}{ccll} miles&minutes\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 55&60\\ 310&m \end{array}\implies \cfrac{55}{310}=\cfrac{60}{m}\implies m=\cfrac{310\cdot 60}{55}`
