This is a basic rate problem where the student is given a table with data and asked to find the rate of travel for 4 trains in order to compare their speed.
Basic Rate Problem is a free educational video by Khan Academy.It helps students in grades 6 practice the following standards 6.RP.3,7.RP.1,.
1. 6.RP.3 : Use 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..
2. 7.RP.1 : Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction (1/2)/(1/4) miles per hour, equivalently 2 miles per hour..
