Welcome back to our series on GMAT quant rate problems. In the last article, we learned about problems involving fuel consumption rates. This article will address rates problems that incorporate geometry concepts. These are speed = distance/time problems where the...
Welcome back to our series on GMAT quant rate problems. In the last article, we learned about the usefulness of “machine hours” for solving problems featuring more than two or three machines. This article will prepare you for questions that involve rates of...
Welcome back to our series on GMAT quant rate problems. In the last article, we studied problems where two objects are moving, either in the same direction or in opposite directions. This article will return to machines and address problems that feature more than two...
Welcome back to our series on GMAT quant rate problems. The last two articles covered machines working together to complete a job. This article addresses problems that have two objects moving at given speeds instead of two machines working at given rates. Recall from...
Welcome back to our series on GMAT quant rates problems. This article will build upon the last and prepare you to easily solve combined work problems. To begin, let’s review the standard formula we learned last time: (1 / c) = (1 / a) + (1 / b) where c is the combined...
