P = $500 R = 8% T = 3 months (3/12)

I = $10

Step-by-step explanation:

Convert the Rate, R to decimal

Convert the time (3 months) to year.

Then use:

Formula: I = P x R xT

I = 500 x 0.08 x 0.25

I  =  $10

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.
