Two cyclists start biking from a trail's start 3 hours apart The second cyclist travels at 10 miles per hour and starts 3 hours after the first cyclist who is traveling at 6 miles per hour How much?
Two cyclists start biking from a trail's start 3 hours apart. The second cyclist travels at 10 miles per hour and starts 3 hours after the first cyclist who is traveling at 6 miles per hour. How much time will pass before the second cyclist catches up with the first from the time the second cyclist started biking? A. 2 hoursB. 4 ½ hoursC. 5 ¾ hoursD. 6 hoursE. 7 ½ hours AnswerThe distance the 1st cyclist travels is 6(3+t) miles, andthe distance the 2nd cyclist travles is 10t miles...where t=the number of hours since cyclist #2 starts.Now solve: 6(3+t)=10t ==> 18+6t=10t ==> 18=4t ==> t=4.5 hrs==> 4.5 hours = 4 hrs 30 minutes
The body travels 2mts in first 2 seconds and 2.2mts in next four seconds what will be the velocity at the seventh second?
heres the average 2.2 seconds
Two airplanes depart from an airport traveling in opposite directions the second airplane is 200 miles per hour faster than the first after2 hours they are1100 miles apart find the speed of the airps?
They separate at the rate of (1100/2) = 550 miles per hour.x + (x+200) = 5502x + 200 = 5502x = 350x = 175Their speeds are 175 mph and 375 mph.
Two boats leave the port at the same time the first boat travels due east at 14mph and the second boat travels at 28mph inthe direction of N30degrees Ehow far apart will the boats be in 12 hr?
After 12 hours, the first boat is at a distance 14*12 = 168 miles east of the port. The second boat is at a distance 28*12*cos(30) = 291.0 miles north and 28*12*sin(30) = 168.0 miles east of the port. Since their Eastward displacement is the same, the distance between the two is the Northwards displacement of the second boat = 291.0 miles.

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).
Explain why thunder is heard after the lightning is seen?
Thunder is sound- it travels at the speed of sound- about 1100 feet per second. Lightning is light- it travels at the speed of light- about 186,000 miles a second. The light is faster, gets there first.
If a cannon fires at a great distance from you why do you see the flash before you hear the sound.?
you see the flash of light first because light travels faster that sound. light travels at 299,792,458 meters per second whaile sound only travels at 340.29 meters per second.

What if an object is traveling faster than another?
Object will get there first.
Why do you see fireworks before hearing them?
We see the firework works first because the because burning emits light . It is a fact that it travels faster than sound . So the sound energy produced during the burning of fire work reaches us late . So we hear the sound after vizualizing it.
You see the cricket ball hitting the bat first and then hear the sound?
Light travels faster (much faster) than sound.
Why you see a distant event before you hear it?
Because the speed of light is much faster than the speed of sound. Therefore, when the light from that event reaches your eyes, you see it. Then later, the sound from the event reaches your ears, and you hear it. Basically it's just because light travels faster than sound.
What accounts for the time difference between seeing and hearing a fireworks display.?
The time difference is due to the differences in the speed of light and sound. Light travels near 300,000,000 meters/second where sound travels 343 meters/second. Light travels almost one million times faster than sound therefore it reaches you first.
Why do you see the lightning first if you are far away?
Because light travels much faster than sound.
When TV is switched on sound is heard first but light travels faster than sound why?
The reason you hear sound before the picture is that your speakers will work immediate as your screen needs a second or two to start up.
What is the difference between objects speed and velocity?
i think its that velocity is the rate at which the speed "speeds" up. so if you have an object that is going metre per second per second, it means that at the first second it travels 2 metres and the second second it goes a total of 6 metres, because in the time period of the second second it travelled 2 metres faster than the first. so in the third second it would go a totl of 14 m, and so on so forth
