OK so basically when converting 2 meters per second to kilometers per hour you will get 7.2 kilometers per hour. OK so times that by 4 and you will get 28.8 kilometers in 4 hours.
Answer:50
Step-by-step explanation:
7.5 x 2 = 15
25 x 2 = 50
A*5+b*2=145
a +b =50 | * -2
5a +2b=145
-2a -2b = -100
----------------------
5a-2a = 145-100
3a= 45
a=45:3
a=15 questions are worth 5 p
b=50-15=35 questions worth 2 p
