Wendy can wash a car twice as fast as jason. when they work together, wendy and jason can wash a large van in 2 hours. how many hours would it take jason to wash the van by himself?

Answer-

Jason will take 6 hours to was the car alone.

Solution-

Given that Wendy can wash a car twice as fast as Jason, i.e time taken by Jason is twice than that of Wendy for doing a same work.

Let us assume that,

Jason alone will take 2x hours, so Wendy alone will take x hours

So, the amount of work done by Jason in 1 hour is

Likewise, the amount of work done by Wendy in 1 hour is

Net work done by both in one hours is,

So, working together they will do th of work in 1 hour.

Then, the total time taken by them for completing the task or doing 1 job,

But, given in the question that they take 2 hours to complete the job, so

So, Wendy will take 3 hours to complete the task and Jason will take (3×2)=6 hours.

rick would give her the best deal as he will charge $8.88 per hour
