7.5
Step-by-step explanation:
it's basically just 15 divided by 2
Answer:
4 mph
Step-by-step explanation:
Let :
Boat speed = 20 mph
speed of current = x mph
Distance against current = 2 miles
Distance with current = 3 miles
speed against current will be ; 20 - x
speed with current will be ; 20 + x
Time =distance / speed against time against = time with current
Solving Mathematically ;
2/(20-x )=3/(20 +x)
2(20+x )= 3( 20-x )
40+2x = 60-3x
3x +2x=20
5x=20
x = 20 / 5
x = 4 mph
Speed of current = 4 mph
I think the question meant if he added 3/4 of the ingredients, in which case it he needs to add two more.
Answer:
C
Step-by-step explanation:
It closely resembles to a sphere.
The answer is 156.9. Because if it is the hiper x-43 and the maxiumum speed is 6750 you need to square root it then divide it.
