Answer:
5-35n
Step-by-step explanation:
5-35n
Just open the parenthesis and multiply by 5.
16.004 = (1 x 10) + (6 x 1) + (0/10) + (0/100) + (4/1000)
Hope this helps ;)
Let:
v = Olga's speed
t = the time Anna spent going to school (3 km/hour)
t/2 = the time Anna spent running back home with speed of 6 km/hour
So, t + t/2 = 3t/2 is the total time
In the meantime distance = speed*time and the both made the same distance we can put it as:
3t + 6*(t/2) = (3t/2)*v
6t = (3/2)tv divide both sides by t
(3/2)v = 6
v = 2*6/3
v = 4 km/hour
Olga's speed was 4 km/hour.
