Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
2t + 8 ≥ -4(t+1)
PEMDAS
2t + 8 ≥ -4t - 4
2t + 12 ≥ -4t
12 ≥ -6t
-2 ≤ t
Convert 97.5 inches to centimeters. 97.5 in=247.65 cm. The area is 247.65 inches^2. Hope this helps! ;)
