A car drives 40 miles on local roads at 20 mph, and 180 miles on the highway at 60 mph, w Your dinner bill is $25 before tax. Th

Anastasy [175]

Answer and Step-by-step explanation:

$Let's~solve~your~problem!$

Formula :

$speed=\frac{distance}{time}$

Solving for time:

$Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20} = 2~hours$

$Time~taken~to~cover~180~miles~on~the~highway~=$ $\frac{180}{60}=3~hours$

$Total~Time~=~5~hours$

Solving for distance:

 $Total~Distance=40 + 180 = 220$ 

Average speed:

 $\frac{Total~distance}{Total~time} = \frac{225}{5} = 44~miles~per~hour$

1675 at 4.6% for 4 years What is the balance

Yuri [45]

Amount of Interest (I) = P * R * T /100
I = 1675 * 4.6 * 4 /100
I = 308.20

Balance = Initial amount + Interest amount
B = 1675 + 308.20 = 1983.20

In short, Your Answer would be $1983.20
