Question

Light travels at a speed of about 3.0x10^8 meters per second. How far does light travel in 1 hour??

Please show work!!!!!!!!

Answer 1

we used physics formula v = d / t

d = distances (m)
v = velocity (ms^-1)
t = time (s)

v = d / t

make the d the subject

v × t = d / t ×t
d = vt

and then substitute

v = 3.0 × 10^8 ms^-1
t = 60s (changing hours to seconds)
d = ??

d = 3.0 × 10^8 × 60
d = 18 × 10^9m

and there is your answer
