A speed walker covered 4 1/2 mi in 3/4 hour. How far will he walk in 3/4 hour if he walks?

Given:

Consider the complete question is "A speed walker covered mi in hour. How far will he walk in 3/4 hours if he walks twice as fast?"

A speed walker covered mi in hour.

To find:

Distance covered by him if in 3/4 hour if he walks twice as fast.

Solution:

We have,

It means a speed walker covered mi in hour.

If the speed is twice then he can cover double distance is same time.

Distance covered by him if in 3/4 hour if he walks twice as fast is

Therefore, distance covered by him is 9 mi.

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.
