Alice’s journey to work every morning involves getting a bus and then walking for 20 minutes to get to the office. Yesterday she missed the bus and had to catch the next one. She then walked to her office in three quarters of the normal amount of time. She arrived at work 15 minutes later than usual. Which of the following could explain the difference in Alice’s arrival time?

c.   x=2.4cm

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.
