Answer:
1.5 km/hour
Step-by-step explanation:
d is the David's speed in still water
c is the speed of the current
Going with the current, he travels d+c km per hour.
Going against the current, he travels d-c km per hour.
d+c = (20 km)/(2.5 hours) = 8 km/hour
d-c = (20 km)/(4 hours) = 5 km/hour
Add the equations to eliminate the c terms
d+c = 8
d-c = 5
----------
2d = 13
d = 6.5 km/hour
c = 8-d = 1.5 km/hour

Answer:
y= -3.6
Step-by-step explanation:
-9.5(1.4)-2.5y=-4.3
-13.3-2.5y=-4.3
-9=2.5y
y=-3.6
256pi
sqroot 256 = 16
16 * 2 = 32
The diameter of the circle is 32
