Answer:
It will take 1.47 hours for the horse and clown to collide
Step-by-step explanation:
They are driving toward each other, in opposite directions.
So to find their speed of approximation, we add their speeds.
19 mph + 15 mph = 34 mph.
This means that each hour, they are 34 miles closer.
How long it takes for them to find each other if they are 50 miles apart?
1 hour - 34 miles
x hours - 50 miles
It will take 1.47 hours for the horse and clown to collide
Plug x=3 in the first equation to find y:
4(3)+5y=2
y=-2
so a=-2
Next, plug x=3, y=-2 in the second equation to find b:
6(3)-2(-2)=22
b=22
The prime factors of 6 are 2 and 3. So for a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3. So, all of the prime factors are even, of course.
