Answer:
$1497.56
Step-by-step explanation:
<em>There are 52 weeks in a year.</em>
$26.88 * 52 = $1397.76
<em>Alma pays $24.95 every 3 months on oil so she does this 4 times a year.</em>
$24.95 * 4 = $99.8
<u>$1397.76 + $99.8 = </u><u>$1497.56</u>
1,497.06
1,397.26 in gas, cuz 52 weeks in a year (sorry if I multiplied wrong), and $99.80 for oil, cuz 12 months in a year. So the total is 1,497.06
50 meters per second
3600 seconds per hour
1000 meters per km
50/1000 = 0.05
1/3600 = .0002777
0.05/0.0002777 = 180km per hour
180*4 = 720km in 4 hours
The grinding of the material
