We can set up a system of equations to solve this.
120b + 90d = 270
60b + 110d = 265
To cancel out b, first make the b terms equal.
60b · 2 + 110d · 2 = 265 · 2
120b + 220d = 530
Now subtract the equations.
120b + 90d = 270
-120b + 220d = 530
---------------------------
-130d = -260
Solve for d.
-130d/-130 = -260/-130
d = 2
Now put the value of d in one of the equations.
60b + 110d = 265
60b + 110 · 2 = 265
60b + 220 = 265
60b + 220 - 220 = 265 - 220
60b = 45
60b/60 = 45/60
b = 0.75
Each candy bar sells for $0.75
Hope this helps! :)

Explanation and work:
To find the answer for this question, we would use the numbers we know that was provided in the question and use it to get us the answer.
The equation we would use in this type of question is the Pythagorean Theorem.
Pythagorean Theorem:
a² + b² = c²
When you draw out the different locations, it would end up looking like a triangle since you trying to find the diagonal line from the grocery store to the house. In the triangle, it would be the hypotenuse. I will put a picture below.
Lets start solving:
1.8 would be plugged into "a"
2.4 will be plugged into "b"
(1.8)² + (2.4)² = c²
↓ ↓ ↓
3.24 + 5.76 = c²
↓
9 = c²
↓
√9 = √c²
↓
3 = c
3 miles would be your FINAL answer.

Answer:
90 Minutes
Step-by-step explanation:
If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount
30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.
