Answer:
option b
Step-by-step explanation:
sine all sides of a square are equal, AD = 8 too
therefore with pythagoras theorem,
AD^2 + AB^2 = BD^2
8^2 + 8^2 = BD^2
64 + 64 = BD^2
128 = BD^2
BD = root of 128 = 8 root 2 (b option)
Pump A = 45 mins
Pump B = 35 mins
Pump A and B = (45 x 35) / ( 45 + 35) = 19.69 mins (nearest hundredth)
