One car travels 20 km hr faster than another While one of them travels 240 km the other travels 180 km Find the speed of the fast car?

Difference in distance covered = (240 - 180) = 60 km
But since speeds differ by 20 kph, difference in distance is (20 x #hours).
60 = 20 x #hours
#hours = 60/20 = 3 hours.
Fast car covers 240 in 3 hours ---> 80 kph
Slow car covers 180 in 3 hours ---> 60 kph

One car travels 40 kmhr faster than another While one travels 150 km the other goes 350 km Find the speed of the slower car?
30 km/hr
Is 8.016 faster than 8.16?
They are both numbers, not velocities. Neither is faster than the other.

An employee travels 26 miles round trip from his home to work If he works 5 days a week how many miles does he travel in a week?
The employee travels 26 miles in one day. Since the employee travels for five days each week, he travels 26*5, or 130 miles in one week.(This only considers the miles traveled to and from work, since no information is given about any other travel.)
What is the equation used to calculate the distance something travels?
The equation used to calculate the distance something travels is given below . we know, speed = distance /time . distance = speed X time in meters /km /or any other unit of length.

30 km/hr
Can a sound be faster than a other sound?
yes, sound travels faster in liquids and solids than in gases e.g. faster in water than through air. The denser the solid, the faster the sound travels.
In what material does sound travel through the fastest?
There are too many 'materials' to list but generally, sound travels faster in solids than in liquids, and faster in liquids than in gases. In other words, the denser the material, the faster sound travels.
What material does sound travel through the fastest?

What is faster the speed of lightning or the speed of sound?
Lightning travels approximately at 60,000 miles a second (96,560 kps), while sound travels at a pokey one-fifth of a mile per second (20 kps). I think you might have actually been referring to light, not lightning, which travels at 186,411 miles per second (300,000 kps). In other words, light travels almost a million times faster than sound.
Does sound travels faster in fresh water air steelor the same speed in all of the above?
sound travel faster in air then in any other
Why sound waves travel faster in water?
Because sound travels by the vibration of molecules of medium , and in water the molecules are close to each other as the inter molecular spaces are small so the vibration transfer from one molecule to another faster than air.
What type of wave travels fastest?
Electromagnetic radiation travels at a speed that's not only faster than any other wave,but is also the "universal speed limit", faster than which nothing can move.
Why does sound travel faster through iron than thought air?
I believe that sound travels faster through iron because it bounces off the sides, and causes it to travel faster, reaching the other side.
Which travel faster light or sounds?
Light travels considerably faster.Sound travels at about 343 meters per second. Light travels at 299,792,458 meters per second.Light in vacuum travels about 876 thousand timesas fast as sound in air.If you meant to ask if light or sound travels faster then this is the answer:Light travels faster, with a speed of 300,000,000 m/s (which is equal to 300,000 km/s, or 186,282 miles per second). Sound, on the other hand, travels at a speed of 340 m/s (which is equal to 1126 ft/s).
Why does higher the temperature makes the sound travels faster in the air?
All other things being equal, Its the increased vibration of the air molocules at higher temperature that allows faster transmission of the pressure wave.
Does sound travel faster in outer space or in air?
sound travels faster through a solid because the particles are right next to each other and so it is faster to vibrate whereas air particles are further apart and take longer to travel. So yes it would travel through the ground faster than air.
