Answer:

1 hour working on problems, 3 hours reading

Explanation:

the question is not complete:

Bob is a hard-working college freshman. One Tuesday, he decides to work nonstop until he has answered 200 practice problems for his chemistry course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem.

Time                   Total Problems Answered       Marginal gain

8:00 AM                         0    

9:00 AM                        80                                        80

10:00 AM                     140                                        60

11:00 AM                      180                                        40

Noon                          200                                        20

Since Bob's is able to answer more than 70 questions per hours only during one hour (from 8 to 9 AM), he can benefit more from reading the next 3 hours. Reading would be equivalent to answering 210 questions, while Bob was only able to answer 120 more questions in the following 3 hours.

slavikrds [6]

Answer:

<u>Administrative delay</u>, <u>restrict trade</u>

Explanation:

An administrative delay refers to a procedural delay which occurs when a foreign product is allowed to be sold in the domestic market. In such a case, a waiting period gets imposed before the expiry of which the foreign exporter cannot enter the domestic market and sell it's products.

This delay is in the form of going through a very time consuming and cumbersome process of availing licenses, permits, sanctions, etc from the government.

Administrative delay acts as a barrier to trade since in a way it discourages the exporters from exporting their products to a foreign market owing to a tedious cumbersome time consuming procedure.

The practice is used by governments to restrict trade.
