How long will your trip take if you travel 650 km at an average speed of 80 km/hr?

We know that the distance, speed, and time it takes are all connected.  Here are the three forms of the equation that describes the connection:

-- Distance = (speed) x (time)

-- Speed = (distance) / (time)

-- Time = (distance) / (speed)

Since the question is asking "How long ?", the answer will be a time.  The easiest equation to use is the third one:

Time = (distance) / (speed)

Time = (650 km) / (80 km/hr)

Time = (650/80) ( km / km/hr)

Time = 8.125 hours

( Time = 8 hrs 7 minutes 30 seconds )

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
