Hi All,
We're told that Albert can travel 200 miles in 4 hours. We're asked how many hours it will take Albert, traveling at the same constant rate, to travel 350 miles? The math behind this question can be approached in a number of different ways, including as a rate or as a ratio.
At a rate of 200 miles in 4 hours, Albert will travel 50 miles in 1 hour. Over a 7 hour trip, Albert would travel...
(7 hours)(50 miles/hour) = 350 miles
Final Answer: C

Since Albert has a rate of 200/4 = 50 mph, it will take him 350/50 = 7 hours to travel 350 miles.BTGModeratorVI wrote: ↑Tue Mar 31, 2020 5:16 amIf Albert can travel 200 miles in 4 hours, how many hours will it take Albert, traveling at the same constant rate, to travel 350 miles?

One approach is to use equivalent ratios
Let t = time to travel 350 miles
Our ratio is distance traveled/time
We get: 200/4 = 350/t
Cross multiply to get: (200)(t) = (4)(350)
Simplify: 200t = 1400
Solve: t = 7 hours
Answer: C
Cheers,
Brent
