Their closing speed is the total of the speed of the bus and the speed of the car:
... closing speed = (bus speed) + (1.4 times bus speed) = 2.4 × bus speed
The closing time is inversely proportional to the closing speed. When the bus alone covers the distance, the time required is 40 minutes. When the distance is covered 2.4 times as fast, the closing time is
... (40 min)/2.4 = 16 2/3 minutes
The vehicles will meet 16 minutes and 40 seconds after they start..
Let x be the number of hours to fix car.
$80x + 210 = 490
80x= 490-210
80x = 280
x = 280/80
x= 3.5 hours
Hope I helped :)

Answer:
c= 25+0.05m
Step-by-step explanation:
Given that,
The phone company charges a flat rate of $25 per month. In addition they charge $0.05 for each minute of service.
$25 is fixed here and charge $0.05 for each minute of service.
We need to find the equation that can be used to find the monthly charge based upon the number of minutes (m) of service each month.
c= 25+0.05m
Hence, this is the required equation.
