To the nearest cent, how much interest will she earn in 2 years?

Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

10.50 is the interest

Step-by-step explanation:

B = p(1 + r)^t

P = 50

r = .10

t = 2

B = 50(1 + .1)^2

  = 50(1.1)^2

  = 50(1.21)

   = 60.5

But we want to know the interest and this is the balance

60.5- 50 = 10.5

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.
