The product would be 12 and 14/21 plus 18/21 so 18+14 is 32/21 then you can simplify
Well, if you cut a circle in 4 parts, each part will equal 90 degrees. But if you cut one of those parts in half again it will cut the degrees in half. Thus, making the degrees of that half a part 45. Your answer should be 45 degrees.
Answer:
!0.00...........360 km..........................
.........>........................................<......11.30
55km/h 130 km/h
Step-by-step explanation:
in a one and a half hour the distance between the train will be
360- 55*1,5=277.5 km
in an hour the distance between the trains is less with 55+130=185 km
to meet the trains , the distance between them should be zero
277.5 - 185*x=0
+185 x +185 x
277.5=185x
x=277.5/185 hours
x= 1.5 hours after 11.30
They meet at 13.00
the distance will be 55*3 =165 km from the station A
