A triathlete competes in a triathlon in which the swimming, biking, and running segments are the same length. The triathlete swims at a rate of 3kph, bikes at a rate of 20kph, and runs at a rate of 10kph. What is the triathlete's average speed? Hint: Its not 11kph

33kph

Step-by-step explanation:

The question here is asking for the average speed of a triathlete during a triathlon

To find the average speed we simply add the average speed of each activity

10 + 20 + 3 = 33

So we can conclude that the average speed of the triathlete during the triathlon is 33kph

Option: B is the correct answer.

The simplest inequality that represents this situation is:

                 B.      x > 9

It is given that:

Luke can build 2 tables in a day.

Also ,  he has to build more than 18 wooden tables for a client.

i.e. if he works for x days.

Then the total number of tables he build is: 2x

i.e.

( Since he has to build more than 18 tables)

i.e. on dividing both side of the inequality by 2 we get:
