Answer:
11
/20
Step-by-step explanation:
Step 1- We can't subtract two fractions with different denominators. So you need to get a common denominator.
So we multiply 3 by 10, and get 30.
Then we multiply 2 by 4, and get 8.
Next we give both terms new denominators -- 4 × 10 = 40.
So now our fractions look like this:
30
/40
−8/40
Step 2- Since our denominators match, we can subtract the numerators.
30 − 8 = 22
So the answer is:
22
/40
Step 3-
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? Yes we can!
11
/20 is the answer
Let x be equal to Jim's travel time
Let x + 2 be equal to Joan's travel time
distance = speed*travel time
6(x + 2) + 8x = 33
6x + 12 + 8x = 33
14x = 21
x = 21/14 = 3.5
3.5 hrs is the hours that Jim have been running until he met Joan.
