Given Information:
Distance = 160 miles
Required Information:
Rate = r = ?
Answer:
Rate = r = 20 mph
Step-by-step explanation:
Recall that the rate is given by
Rate = distance/time
It is given that the same trip would have taken 2 hours longer if he had decreased his speed by 4 mph.
Mathematically,
Simplify the equation
Now we are left with a quadratic equation.
We may solve the quadratic equation using the factorization method
So,
OR
Since rate cannot be negative, discard the negative value of r
Therefore, the rate is
9514 1404 393
Answer:
- monthly payment $690.25
- total interest $123,490
- total repaid $248.490
- difference from rent $9.75
Step-by-step explanation:
Frank's monthly payment will be $690.25.
The total of all payments will be $690.25 × 360 = $248,490.00.
The interest Frank will pay is $248,490 -125,000 = $123,490.00.
The difference between Frank's rent and his loan payment is ...
$700 -690.25 = $9.75
