Answer:
Step-by-step explanation:
When you add integers you have either positive integers or negative integers. When you add positive integers, you just add normal. When you have negative integers, you have to see if the the larger number is positive or negative that will tell you if your answer is either negative or positive. Then you turn the negative into a positive then change the addition sign to a subtraction sign then solve.
The answer is the first option.
Let the time at which the two friends are at the same distance be x. With this representation, the equation would be,
3x = 4(x - 5/60)
The value of x from the equation is 0.33, which has a units of hours. Since, we are in minutes.
minutes = (0.333)(60)
minutes = 20
Answer: 20 minutes
