To prepare for a bicycling event, you warm up each day at a moderate pace then you ride hard for a number of miles. one day you
vovangra [49]

Answer:

The total distance covered is 15.6 miles.

Step-by-step explanation:

One day you warm up for 15 minutes at a pace of 0.1 miles per 25 seconds.

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. If the relationship between the magnitudes is direct, like in this case, the direct rule of three can be applied as follow:

a ⇒ b

c ⇒ x

Then x=\frac{c*b}{a}

First, the simple rule of three can be applied in the following way: if 1 minute equals 60 seconds, 15 minutes equals how many seconds?

seconds=\frac{15 minutes*60 seconds}{1 minute}

seconds= 900

So now you can apply the following rule of three: if in 25 seconds you travel 0.1 miles, in 900 seconds how many miles do you travel?

distance=\frac{900 seconds*0.1 miles }{25 seconds}

distance= 3.6 miles

If you then ride hard for 12 miles, the total distance traveled will be the sum of both:

3.6 miles + 12 miles = 15.6 miles

<u><em>The total distance covered is 15.6 miles.</em></u>

Answer:

<u><em>The difference between iPhone 11 and Spinal cord repairence is 99,300$</em></u>.

Step-by-step explanation:

To be honest, this is a really weird question.  But a<em><u> spinal cord injury</u></em> can cost up to <u><em>100,000$ a year</em></u>.  And an<u><em> iPhone 11 cost around 700$</em></u>.  It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol.  And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.
