# How To Solve A Rate Problem It's adaptive, fun and finds the right teacher for you.

Grockit’s analytic capabilities and adaptive technology identifies students' strengths and weaknesses, focusing the student's study time.

A.3.a Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane.

For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours?

A.3.b Solve unit rate problems including those involving unit pricing and constant speed.  At this rate, how much snow could 8 plows remove in 5 minutes? Grockit, an online test prep game, is the smartest way to study for your test. A.2Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. A.3Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. In this section we are going to look at an application of implicit differentiation.Most of the applications of derivatives are in the next chapter however there are a couple of reasons for placing it in this chapter as opposed to putting it into the next chapter with the other applications. “Unit rate” is a comparison of any two separate but related measurements when the second of these measurements is reduced to a value of one.In questions where individuals work at different speeds, we typically need to add their separate rates together. This doesn’t mean wasting time and writing each and every one out, but rather simply recognizing their existence. If moving in the same direction, we instead subtract their speeds to find the relative velocity. Train A traveling at 60 m/hr leaves New York for Dallas at 6 P. Train B traveling at 90 m/hr also leaves New York for Dallas at 9 P. Rate of Train C = 720 miles/ 6 hours = 120 miles/hour. Many times you may be asked to calculate the number of workers would be need to complete a certain task. 131,200Instead of man-hours, here we want to interact plow-minutes.Students can practice in adaptive solo games, play social learning games with peers, and work with experts that match their specific needs.1. Complete GMAT RC Questions in less than 1 minute and 50 seconds2. To find this, we find the reciprocal of 13/42.42/13 hours/truck = 3 3/13 hours/truck. Objects moving at given speeds on the GMAT usually travel toward or away from each other. To catch up the 180 miles, it will take Train B 6 hours. Remember the question is asking for the number of hours to fill 1 truck, NOT the number of trucks completed in 1 hour. In the three hours from 6pm to 9pm, A gets to mile marker 180.
