Answer:
5 hours cuz 75 divided by 15 is 5 or 15 x 5 is 75
Let's first turn all the words into numbers:
Two and four tenths = 2.4
One and six tenths = 1.6
Four and one tenth = 4.1
Now lets represent "a number" as x.
Then translate the wording into a linear equation:

Simplify and isolate the variable:

Divide by 0.8
x>1.375 or x>1 3/8
-8t+6+6t=5t-2
-2t+6=5t-2
-2t-5t=-2-6
-7t=-8
-7 -7
T=1.14 or 1 1/7
Answer:
17/24
