Answer:
4 km
Step-by-step explanation:
T = time
D = distance
S = speed
the forumla to find the distance is
T * S = D
manipulate the equation for this problem:
D/S = T
Plug-in the known values
D = 12.5 km
S = 50kph
12.5km/50kph
cancel units and simplify
4 km
I don’t know what the answer is but I just came by to say I hope you have a great day
Answer:
y = 3z -x^3
Step-by-step explanation:
Mn - 4m - 5n + 20
(mn - 4m) + (-5n + 20)
m(n - 4) + (-5n + 20)
m(n - 4) - 5(n - 4)
(m - 5)(n - 4)
So mn - 4m - 5n + 20 completely factors to (m - 5)(n - 4)
