When a dog noticed a fox, they were 60 meters apart. the dog immediately started to chase the fox at a speed of 750 meters per minute. the fox started to run away at a speed of 720 meters per minute. how soon will the dog catch the fox?

The dog catches the fox after 2 Minutes.

Step-by-step explanation:

Let the dog distance to the point where he catches the fox=x

The Dog's Speed=750 meters per minute.

Therefore: the dog's time,

Since, they were 60 meters apart initially, the fox distance to the same point =x-60

The fox's Speed=720 meters per minute.

Therefore: the dog's time to reach that point,

Since the time taken to reach the point is equal,

Therefore: Time taken=

The dog catches the fox after 2 Minutes.

the answer to this question is 3/19

step-by-step explanation:

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
