<span>So, the formula for this problem is 10/x =40/64. You can solve for x by cross multiplication so, you end up with 40x=640 with x=16. So Justin should charge his friend $16.00.</span>
There are a total of 48 students so what we do is divide by 4. Then you just multiply times the 3/4 left. We get 48 divided by 4 to be 12. So 12 times 3 is....36. 48-36=12. 12 girls.
If 3 ft = 1yard
? = 16 yards?
Thats 
The common values cancel each other out and you'll have 48 feet :)
The cattle train
speed - 36.5 km/h
time - x h
the passenger train
speed - 29.2 km/h
time - (2.4+x) h
The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.

The passenger train travelled for
12 hours before the cattle train caught up.
