Jenny has tossed a fair coin 25 times. It has landed on heads every single time. Is this possible? Why?

It is possible, but very unlikely.

Also, it is very likely the next flip will be Tails

This is because probability does not say if it is possible, but how likely it is!

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.
