Answer:
D
Explanation:
Alright, so we know that they can unload 25 trucks in 5 hours.
If we do 25/5 We find out that they can unload 5 trucks per hour
Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is equivalent!
After evaluating the available answers, you can find that answer D lines up with our first assumption!
Every 1/5th of an hour the Fast-Pack people can unload a truck!
We can calculate this by writing:
1/5*25=5
Please let me know if you have any confusion! :)
