Answer:the son working alone will take 1¹/₂ hours
Step-by-step explanation:
Step 1
let x represent the hours that the son needs to wash and wax the car alone thus his rate is 1/x cars per hour
While
the rate of the father is 1/3 cars per hour
, working together rate is 1/1 cars per hour.
Step 2
Writing it mathematically, becomes
1/x + 1/3 = 1/1
Dividing through by 3x so all denominations can be rqual to 1 , we have
3 + x = 3x
3= 3x-x
3= 2x
x= 3/2
Therefore the son working alone will take 1¹/₂ hours
