The episodes of a TV program are each 50 minutes long.
Nimfa-mama [501]

Answer:

3 hours 20 minutes

Step-by-step explanation:

first multiply 50 by how many episodes were watched

50 * 4 = 200

then devide it by 60 (60 minutes in an hr)

200 / 60 = 3 with a remainder of 1/3

meaning that it is 3 1/3 hours, to convert this into minutes, just devide a full hour (60 minutes) by 3

60 / 3 = 20

therefore the answer is 3 hours and 20 minutes
