As you drive to school, suppose the probability that you have to stop at a traffic light at a specific intersection on your way is 0.75. In a given week you approach this intersection 10 times. Assume that each time you approach the intersection the probability that you have to stop for the red light is the same and is independent of any other approach. What is the probability that you will have to stop for a red light at this intersection at least half of the time in a given week of driving to school

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.
