55 mph
We know that the time traveled is 5 hours, since a car going 10 mph faster travels an extra 50 miles over the same amount of time.Dividing 300 miles by 5 hours, we get 60 mph. Since the car is traveling 10 mph, the car is traveling 70 mph.
The red car travels 20 m in 2 secs so its average velocity is 10 ms-1, which is greater than the blue car.

Depends entirely on the speed at which you are traveling. Faster the speed, shorter the time.
JOhn is driving at 65 mph and Bob is driving at 55 mph.
Sound travels faster downwind. The speed at which sound travels is relative to the medium it is moving through. When sound is traveling upwind, you subtract the wind speed from the speed of sound. When it is traveling down wind you add the wind speed.
Sound travels faster through air. Though sound travels farther through solid objects (vibrations), it is faster when traveling through air waves.
The advantages of steamboats over horse traveling was that steamboats were much faster and cheaper.
light travels faster in vacuum.
sound travels faster through water. it is also affected by temperature and sea level. the speed of sound or mach 1 is reached roughly around 744 MPH plus the Mass of the object that is traveling at that speed.
A Worm travels faster than a Snail.

lightning travels faster. Light is faster than sound.
Sound travels faster when traveling through a headset than in plain air. The speed of sound in air is a little more than 1000 feet per second. Sound transmitted electronically through a headphone circuit travels much faster.
Light travels faster than sound ... about 875,000 times faster. Nothing travels faster than light.
Nothing is faster than the speed of light in a vacuum (other household appliances are left as an exercise for the reader). Electricity travels at essentially the speed of light in the conductive medium it's traveling through, but not faster.
