When fritz drives to work his trip takes 30 ​minutes, but when he takes the train it takes 20 minutes. find the distance fritz travels to work if the train travels an average of 12 miles per hour faster than his driving. assume that the train travels the same distance as the car. fritz travels nothing miles to work?

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.
