Answer: Plan A lasts for 30 minutes and Plan B lasts for 45 minutes.
Step-by-step explanation:
Let's consider plan A is x, and Plan B is y. For Monday, according to the conditions, the equation will be 3x+ 2y= 3, and for Tuesday, the equation will be 5x+6y= 7. Now, multiplying the first equation with five and second equation with three we get, 15x+10y= 15 and 15x+ 18y= 21. Subtracting these two equations, we get, 8y= 6
Or y= 3/4. Putting the value of in any equation, we get the value of x, which is 1/2.
1/2 hours means 30 minutes and 3/4 hours means 45 minutes. Thus Plan A is 30 minutes and Plan B is 45 minutes.
