Answer:
2^3 =8
Step-by-step explanation:
2*2 =4
4*2 =8
2*2*2 =8
2^3 =8
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.
Answer:
Hence the pricing for each product will be taronges with 2 euros and mandarins with 2.5 euros.
Step-by-step explanation:
Given:
2 kg of taronges and 3 kg mandarins cost 11.5 euros
3kg taronges and 2 kg mandarins cost 11 euros
To Find:
Price for each product
Solution:
<em>Consider </em>
<em>Taronges =x euros</em>
<em>Mandarins=y euros</em>
So by given condition,
....................equation(1)
and
...........equation (2)
So , using substitution method,

.......equation (3)
Using above value in equation(1) we get ,

)
y=2.5 euros
Using above value in equation(3) we get ,



x=2 euros
