A train leaves Miami at 3:00 PM. A second train leaves the same city in the same direction at 8:00 PM. The second train travels

Anika [276]

Answer:

The first train travels at 58 mph and the second train travels at 203 mph.

Step-by-step explanation:

The first train left Miami at 3:00 PM.

The second train left Miami at 8:00 PM.

Let the speed of the first train be x.

The second train travels 145 mph faster than the first, that is 145 + x

The second train overtakes the first at 10:00 PM

This means that at 10:00 PM, they were both at the same location.

That is 7 hours after the first train left and 2 hours after the second train left.

Speed is given as:

s = d / t

where d = distance traveled and t = time taken

For the first train, after 7 hours traveling at speed x:

x = d / 7

=> d = 7x _______(1)

For the second train, after 2 hours, traveling at speed 145 + x:

145 + x= d / 2

=> d = 290 + 2x ____(2)

Equating (1) and (2):

7x = 290 + 2x

=> 7x - 2x = 290

5x = 290

=> x = 290/5 = 58 mph

Therefore, the first train travels at 58 mph and the second train travels at 203 mph (58 + 145)

Kylie owes $1,700 on her credit card. The bank charges a monthly interest rate of 0.925%. If Kylie wants to pay off her credit c

aksik [14]

Answer:

$221.44

Step-by-step explanation:

As the bank charges a <em>monthly </em>interest, we cannot calculate a simple or compound interest over the 8 month period. As the balance will decrease each month as Kylie makes payments, the interest applied each month will also decrease. Therefore, we have to use:

<u>Monthly Payment Formula</u>

$\sf PMT=\dfrac{Pi(1+i)^n}{(1+i)^n-1}$

where:

PMT = monthly payment
P = loan amount
i = interest rate per month (in decimal form)
n = term of the loan (in months)

Given:

P = $1,700
i = 0.925% = 0.00925
n = 8 months

Substituting the given values into the formula and solving:

$\implies \sf PMT=\dfrac{1700(0.00925)(1+0.00925)^8}{(1+0.00925)^8-1}=221.4403207$

Therefore, the monthly payment to the nearest dollar will be $221.44
