Take the horse to overtake the

S_A_V [24]

Answer:

120 km/h

Step-by-step explanation:

Speed in one direction = 40 km/h
Speed on return = x
Average speed = 60 km/h

Let the distance be d

<u>Average speed </u>

2d/(d/40 + d/x) = 60
d/40 + d/x = 2d/60
1/40 + 1/x = 1/30
1/x = 1/30 - 1/40
1/x = (4-3)/120
1/x = 1/120
x = 120 km/h

3. Siti and Mary shared $35 in the ratio 4:3.<br> How much money did Siti receive?

Mashcka [7]

Answer:

$20

Step-by-step explanation:

First we will change the ratio so that we are finding how much money Siti receives to the total amount of money.

$4:3 \rightarrow 4:(3+4)=4:7$

Now we can solve for how much money Siti receives using a proportion.

$\frac{4}{7} = \frac{\mbox{money Siti receives}}{35}$

We can see that the denominator increases 5 times, so the numerator must increase 5 times too. This means Siti receives $20.
