emerged

I'm a little stuck... Click here to teach me more about this clue!

'came into view' is the definition.
(I've seen this before)

'rolling back mile in 60 minutes' is the wordplay.
'rolling' is a reversal indicator.
'back mile' becomes 'm' (common abbreviation. I am not sure about the 'back' bit.).
'in' means one lot of letters goes inside another.
'60 minutes' becomes 'degree' (I've seen this before).
'm' placed inside 'degree' is 'degreme'.
'degreme' in reverse letter order is 'EMERGED'.

Can you help me to learn more?

(Other definitions for emerged that I've seen before include "Emanated" , "Came out, became known" , "Slowly came out" , "Came forth" , "Deem Reg to have come out" .)
