# Time and Distance Problem from AMC 8: Problem 6 – 2018

Try this beautiful problem from AMC 8. It involves basic statistics and data representation. We provide sequential hints so that you can try the problem.

## Competency in Focus:Â Time and Distance calculation

This problem from American Mathematics Contest 8 (AMC 8, 2018) is based on calculation of time and distance. It is Question no. 6 of the AMC 8 2018 Problem series.

## Next understand the problem

On a trip to the beach, Anh traveled 50 miles on the highway and 10 miles on a coastal access road. He drove three times as fast on the highway as on the coastal road. If Anh spent 30 minutes driving on the coastal road, how many minutes did his entire trip take? $\textbf{(A) }50\qquad\textbf{(B) }70\qquad\textbf{(C) }80\qquad\textbf{(D) }90\qquad \textbf{(E) }100$

Do you really need a hint? Try it first!
Speed = $\frac {distance}{time}$Â  This can be the first hint for this sum. It is one of the important formula in science. Try to use it in this sum……..
So if we use the previous hint the speed would beÂ  r = $\frac {d}{t}$ so , r = $\frac {10}{0.5}$ Â  Â r = 20 mph.
His speed on the highway then is $60$ mph. He drives $50$ miles, so he drives for $\frac{5}{6}$ hours, which is equal to $50$ minutes. Note : 60 miles\hour is equal to 1 mile\minute
I think you already got the answer but if not here is the last hint. The total amount of minutes spent on his trip isÂ  =80 minutes
