Answer:
Yes she can.
Step-by-step explanation:
Val can make 6 slides in an hour.
1/6 * 60 minutes = 10 minutes. per slide
10 20 30 40 50 60 gives you six sldes, 1 every ten minutes.
=====================
In one hour, she can produce 6 slides.
In two hours, she can produce 12 slides (2 * 6 = 12)
Since she only needs 1 hour and 40 minutes to produce 10 slides, she is under her time limit of 2 hours.
