Jordan and Dajia are both completing homework on Deltamath. Jordan started yesterday and completed three problems and is solving the problems at a rate of 2 questions per minute. Dajia waited until today to get started and is solving the problems at a rate of 3 questions per minute. After how many minutes will they have solved the same number of questions?

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
