Ingrid walked her dog and washed her car . She spent 3 times as much time washing her car as she did walking her dog. it took Ingrid 1 1/2 hours to wash
her car .How long did it take Ingrid to walk her dog ?
Equation:
Variable represents:
Wouldnt it be 3.5, because 14/4 as a decimal is 3.5.
Let's first define our variable. Let's say the variable "x" represents the time it took Ingrid to walk her dog.
Given that Ingrid spent three times as much time washing her car as she did walking her dog, we can say that the time it took to wash her car is three times the time it took to walk her dog.
Since it took Ingrid 1 1/2 hours (or 1.5 hours) to wash her car, we can write this as an equation:
3x = 1.5
Now, we need to solve for x to find out how long it took Ingrid to walk her dog.
Dividing both sides of the equation by 3, we have:
x = 1.5 / 3
x = 0.5
Therefore, it took Ingrid 0.5 hours (or 30 minutes) to walk her dog.
1.5/3 = ?
1/4 ×14=56
56-14=42
