Two cars leave the same driveway traveling opposite directions. If one car travels 40
miles per hour and the other travels 45 miles per hour, how long until they are 90 miles
apart?

0.94 hours
1.06 hours
1.5 hours

1.06 hours

Step-by-step explanation:

D=rate*time

r=40,45

d=90

t=idk

40t+45t=90

85T=90

-now divide both sides by 85

85T/85=T

90/85=1.06

SO t=1.06 HOURS

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
