A car travels 75 miles per hour, and a plane travels 15 miles per minute. How far (in miles) does the car travel while the plane travels 600 miles?

50 miles

Step-by-step explanation:

600 / 15

= 40

It takes 40 minutes for the plane to go 600 miles

40 minutes is 40 / 60 hours which is 2 / 3

75 * (2 / 3)

= 50

The car travels 50 miles

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

47 - 90 = 43

43 - 180 = x

x = 137
