Answer:
13104
Step-by-step explanation:
9C2 x 14C3 = 36 x 364
= 13104
The product of the 4 numbers is 0. that means that one or more of the numbers is 0. because they appear in defending order we know that the digit in the ones place is 0. the only common factor of 10 and 15 is 5 so we know that our number is 5 _ _ 0. because they add up to 9 the second 2 digits have to add up to 4. the only two numbers that add up to four and are not the same(they have to be in descending order so it can't be the same digit twice) are 1 and 3 so your license plate is 5310
You must travel at 42 mph for 4 hours
<em><u>Solution:</u></em>
Time varies inversely as rate of motion
Let "t" be the time required
Let "r" be the rate of motion
Then, we get

Where, "k" is the constant of proportionality
<em><u>You travel 3 hours at a rate of 56 mph</u></em>
Substitute t = 3 and r = 56 in eqn 1

<em><u>Find the rate you must travel for 4 hours</u></em>
r = ? and t = 4
Substitute t = 4 and k = 168 in eqn 1

Thus you must travel at 42 mph for 4 hours
