How much does a poster board cost? thats kind of important
Answer:
If 2 mph) 5 hours
If 2.5 mph) 4 hours
If m mph) 10/m hours
If m+2 mph) 10/(m+2) hours
If m/3 mph) 30/m hours
Step-by-step explanation:
To find the time divide the distance (10) by the speed.
10/2=5
10/2.5=4
10/m
10/(m+2)
10/(m/3)=10(3/m)=30/m
If the exam is worth (only!) 15%, then the class average is worth (100-15)=85%.
The grade will then be 54*0.85+0*0.15= 45.9%
The letter grades (if any) will vary from school to school.
