Question

Vicky earned 29.75 for working 3 1/2 hours. What was her hourly wage ?

Answer 1

8. 5

Explanation:

First of all, I converted 3 hours 30 minutes to min. And we have 60 mins in an hour.

Therefore 60 × 3= 180mins +30 mins = 210 mins

So,

If 210=29.75

60=?

Cross multiply

29.75×60/210

=8.5

She's earns 8.5 in an hour
