still water ? Mph what is the speed of the current ? Mph
1 answer:
Answer:
16 MPH boat speed still water
5 MPH current speed
Step-by-step explanation:
84/4 - x = 55/5 + x
x = (84/4-55/5)/2 = 5 mph current speed in MPH
11+5 = 16 is boat speed in MPH

Step-by-step explanation:
92 = 2² × 23
510 = 2 × 3 × 5 × 17
HCF = 2
LCM = 2² × 3 × 5 × 17 × 23 = 23460
Tan(330) = tan(360-30) = tan(-30) = -tan30 = -sqrt(3)/3
