Time taken by car A = 6 hr and time taken by car B is 8 hours
<u>Explanation:</u>
<u />
Given:
Distance, d = 480 km
Let x be the time taken by B to reach the destination:
So,
Time taken by car A to reach the destination = x -2
We know:
Distance = speed X time
speed = 
On substituting the value we get:
Speed of car A = 
Speed of car B = 
Since car A travelled 20 km/hr faster than the car B, the equation becomes:
Multiplying both sides by (x - 2) we get:
Therefore, time taken by car A = x - 2
= 8 - 2 hr
= 6 hr
Time taken by car B = 8 hr
"On Thursday Bernie's dog ate 1/4 lb more dog food than she ate on Wednesday."
That means that on Wednesday, the dog ate 1/4 lb LESS that it ate on Thursday.
"On Wednesday, the dog ate 1 1/3 times the amount of food she ate on Tuesday."
That means that on Tuesday, the dog ate 1 1/3 times LESS that it ate on Wednesday.
Now start with Thursday: "If Bernie's dog ate 1 3/4 lb food on Thursday"
On Wednesday it ate 1/4 lb less that that, so on Wednesday it ate
1 3/4 - 1/4 = 1 2/4 = 1 1/2
On Wednesday it ate 1 1/2 lb.
On Tuesday it ate 1 1/3 times less than on Wednesday. Now we divide 1 1/2 by 1 1/3.
Answer: It ate 1 1/8 lb of food on Tuesday.
Distribute the root 6 to get root 12 plus root 18.
simplify to get 2 root 3 plus 3 root 2
