Answer:how long it took you to get there and the distance between your house and her house
Explanation:
Answer:
Evan drive at speed = 81.67 m/hr
Explanation:
Normal speed of Evan = 70 m/hr
Time taken by Evan to visit his grandmother = 35 min =
hr
Distance covered by Evan =
= ![70\times\frac{35}{60}](https://tex.z-dn.net/?f=70%5Ctimes%5Cfrac%7B35%7D%7B60%7D)
=
miles
According to the problem, one day Evan was running 5 minutes late. So, the time Evan has to visit his grandmother is 30 mins.
To reach on time, Evan should be drive at the speed :
Speed = ![\frac{Distance}{Time}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%7D%7BTime%7D)
= ![\frac{\frac{245}{6} }{\frac{30}{60} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B245%7D%7B6%7D%20%7D%7B%5Cfrac%7B30%7D%7B60%7D%20%7D)
= 81.67 m/hr
Wave motion is the transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points.The dimensions in which a wave propagates energy, The energy transfer
Planets are not hot enough, and that's because they lack the internal energy sources that stars have: thermonuclear fusion (They do emit a little light, mainly infrared light, but nothing compared to the sun)
Planets don't have their own light, so simply they do not emit light, this phenomena goes back to their information. When they are formed, they are much, much less hotter than the stars. In stars, fusion reaction always goes on, in which energy, as well as light is formed, so, there is light for stars to emit for a long time.
