The value of z is .

Step-by-step explanation:

From the given picture it can be observed that both shapes are similar.

Side-length of the similar shapes are proportional.

It can be seen that side with 'z' is corresponding to side with measure 10 on smaller shape and 20 is corresponding to the side with measure 12 on smaller shape.

Using proportionality-, we have

Hence, the value of z is .

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
