For this case we have the following conversion of units:

1mi = 1609m

1h = 3600s

Thus, applying the conversion of units we have:

(23.35 \frac{mi}{h}) (\frac{1609}{1}\frac{m}{mi}) (\frac {1}{3600}\frac{h}{s}) = 10.4 \frac{m}{s}

Then, the distance traveled for 5 seconds is given by:

d = (10.4) (5)

d = 52m

Answer:

he has completed 52 meters of the 80-meter race

$3.00 marked up 72%<br><br>(please show your work!!)<br><br>thank you❤️❤️​
Daniel [21]
<h3>Answer:  $5.16</h3>

==================================================

Work Shown:

72% = 72/100 = 0.72

72% of $3.00 = 0.72*3.00 = 2.16

The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars

-------

We can find this answer through this alternative route:

1.72*3 = 5.16

The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%
