At the factory a baseball card is places in every 9th cereal package a football card is placed in every 25th package what is the

strojnjashka [21]

To figure out this question, look for the first number where both 25 and 9 are a factor of.

25*1 is 25 which isn't a factor of 9, so it won't be 25.
25*2 is 50, which isn't a factor of 9.
75 is not a factor of 9. (you know because you don't get a whole number when you divide 75 into 9.)
100 is not a factor of 9, nor is 125, 150, 175, or 200.

However, 225 is a factor of both 25 and 9. This makes sense because 25*9 is 225.

This means that the first package with both will be the 225th package.

Car A and car B are traveling at different speeds. Car A can travel 175 miles in the same time it takes car B to travel 125 mile

slega [8]

Answer:

The speed of car B is 50 mile per hour

Step-by-step explanation:

Given as :

The Distance travel by car A = 175 miles

The Distance travel by car B = 125 miles

The Time taken by both car A and B is same = T hours

Let The speed of car B = S mile per hour

So, The speed of car A = ( S + 20 ) mile per hour

Now, Time = $\frac{Distance}{Speed}$

So , For Car A ,

T = $\frac{175}{(S + 20 )}$

For Car B ,

T = $\frac{125}{(S}$

So, $\frac{175}{(S + 20 )}$ = $\frac{125}{(S}$

Or, 175 × S = 125 × ( S + 20 )

Or, 175 S - 125 S = 125 × 20

Or, 50 S = 2500

∴ S = $\frac{2500}{(50}$

I.e S = 50 mph

And S + 20 = 50 + 20 = 70 mph

The speed of car A = 70 mph

The speed of car B = 50 mph

Hence The speed of car B is 50 mile per hour Answer
