It will take Levi's dad 1.67 hours to wash the car alone.
Step-by-step explanation:
Time taken by Levi to wash car alone = 2.5 hours
Time taken by Levi and his father together = 1 hour

x be the time taken by Levi's dad.
Levi will contribute 1/2.5 hours and his dad will contribute 1/x to wash the car together.
Dividing both sides by 1.5
It will take Levi's dad 1.67 hours to wash the car alone.
