If you move for 4 seconds, and travel a distance of 360 meters, how fast were you going?

Distance travelled = 360m

Time taken = 4s

We have to find speed

_________________________________

◈ Speed is defined as the ratio of distance travelled to the timr taken.

SI unit : m/s

➝ Speed = Distance / Time

➝ Speed = 360/4

➝ Speed = 90m/s

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
