Answer:
use the Dist = rate * time , formula.. I call it the dirt formula ( Di = rt )
Step-by-step explanation:
since the cars are closing their distance at 10 MPH.. this is question wants to know how long before the cars pass when they are 7 miles apart... this would be the same for a car going 10 MPH and needs to get to a location 7 miles away. sooo..
how long does it take to travel 7 miles at 10 MPH?
it takes 7/10 of an hour.. correct :)
.7 * 60 = 42 minutes
in 42 minutes car 2 will pass car 1
<span>Answer: 100,000,000 + 3,000,000 + 700,000 + 20,0000 + 7,0000 + 400 + 90 + 5 = 103,727,495

<span>Explanation:

<span>1) The expanded form of a number is the split of the number using every digit muliplied by its place value.
</span><span />
<span>2) The first (left most) digit of the given number is 1. It is in the hundred millions place. So, it represents 100,000,000 which is the first number in the expanded form.
</span><span />
<span>3) The second digit (from lef to right) is 0, so its value is 0, and you do not include it in the expanded form.
</span><span />
<span>4) The third digit (from the left to the right) is 3. It is in the place of the millions, so its value is 3,000,000.
</span><span />
<span>5) Next number from the left is 7 and it is in the hundred thousands place, so its value is 700,000.
</span><span />
<span>6) Next is 2, in the ten thounsands place => 20,000
</span><span />
<span>7) Next is 7 in the thousands => 7,000
</span><span />
<span>8) 4 in the hundreds => 400
</span><span />
<span>9) 9 in the tens => 90
</span><span>10) Finally 5 in the ones => 5.</span>
<span /><span>
</span><span>Then number the number is: 100,000,000 + 3,000,000 + 700,000 + 20,000 + 7,000 + 400 + 90 + 5</span>
