A runner completed a 26.2-mile marathon in 210 minutes. a. Estimate the unit rate, in miles per minute. Round your answer to the nearest hundredth of a mile.

Unit rate by which the runner completed the marathon is 0.13 miles per minute.

Step-by-step explanation:

A runner competed a marathon of 26.2 miles in 210 minutes.

we can get unit rate by unitary method.

∵ In 210 minutes a runner completes the distance = 26.2 miles

∴ In 1 minute runner will complete the distance =

                                                                              = 0.125 miles per minute

                                                                              ≈ 0.13 miles per minute

Therefore, unit rate by which the runner completed the marathon is 0.13 miles per minute.

the thesis statement is that sentence or two in your text that contains the focus of your essay and tells your reader what the essay is going to be about. although it is certainly possible to write a good essay without a thesis statement (many narrative essays, for example, contain only an implied thesis statement), the lack of a thesis statement may well be a symptom of an essay beset by a lack of focus. many writers think of a thesis statement as an umbrella: everything that you carry along in your essay has to fit under this umbrella, and if you try to take on packages that don't fit, you will either have to get a bigger umbrella or something's going to get wet.

the thesis statement should remain flexible until the paper is actually finished. it ought to be one of the last things that we fuss with in the rewriting process. if we discover new information in the process of writing our paper that ought to be included in the thesis statement, then we'll have to rewrite our thesis statement. on the other hand, if we discover that our paper has done adequate work but the thesis statement appears to include things that we haven't actually addressed, then we need to limit that thesis statement. if the thesis statement is something that we needed prior approval for, changing it might require the permission of the instructor or thesis committee, but it is better to seek such permission than to write a paper that tries to do too much or that claims to do less than it actually accomplishes.

the thesis statement usually appears near the beginning of a paper. it can be the first sentence of an essay, but that often feels like a simplistic, unexciting beginning. it more frequently appears at or near the end of the first paragraph or two.
