Based on the distance travelled and the time taken, the speed of the train was <u>150 km/h</u>
Speed can be calculated by the formula:
<em>= Distance / Time </em>
Distance = 600 km
Time = 4 hours
Solving will give:
= 600 / 4
= 150 km/ h
In conclusion, the train was going at 150 km/h

Answer: 19 boys and 14 girls liked the Giants.
Step-by-step explanation:
Let be "b" the number of boys who liked the Giants and "g" the number of girls who liked the Giants.
Based on the information given, set up a system of equations:
![\left \{ {{b+g=33} \atop {b=g+5}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bb%2Bg%3D33%7D%20%5Catop%20%7Bb%3Dg%2B5%7D%7D%20%5Cright.)
Use the Substitution method to solve this system of equations.
First, you must substitute the second equation in the first equation and solve for "g":
![(g+5)+g=33\\\\2g=33-5\\\\g=\frac{28}{2}\\\\g=14](https://tex.z-dn.net/?f=%28g%2B5%29%2Bg%3D33%5C%5C%5C%5C2g%3D33-5%5C%5C%5C%5Cg%3D%5Cfrac%7B28%7D%7B2%7D%5C%5C%5C%5Cg%3D14)
<em> </em>And finally, you must substitute the value of "g" into the second equation in order to find the value of "b".
Then:
![b=(14)+5\\\\b=19](https://tex.z-dn.net/?f=b%3D%2814%29%2B5%5C%5C%5C%5Cb%3D19)
