Tim is choosing between two cell phone plans that offer the same amount of free minutes. Cingular's plan charges $39.99 per minute with additional minutes costing $0.45. Verizon's plan costs $44.99 with additional minutes at $0.40. How many additional minutes will it take for the the two plans to cost the same

it will take 200 additional minutes for the two plans to cost the same.

Step-by-step explanation:

Let x represent the number of additional minutes it will take for the the two plans to cost the same.

Cingular's plan charges $39.99 per minute with additional minutes costing $0.45. This means that the total cost of x additional minutes would be

39.99 + 0.45x

Verizon's plan costs $44.99 with additional minutes at $0.40. This means that the total cost of x additional minutes would be

44.99 + 0.4x

For the the two plans to cost the same, the number of additional minutes would be

39.99 + 0.45x = 44.99 + 0.4x

0.45x - 0.4x = 44.99 - 39.99

0.05x = 10

x = 10/0.05

x = 200

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
