Suppose the scale factor you will use to enlarge the map is 5:1. What is the approximate area of the park in your enlarged drawing? Show your work. the are is 21

525

Step-by-step explanation:

If the area of the map is 21 and the scale factor is 5:1, both of the dimensions of the flat park are multiplied by 5. If both dimensions are multiplied by 5, then the area is multiplied by (5*5)=25 times. 25*21=525. Hope this helps!

step-by-step explanation:

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.
