Answer:b
Step-by-step explanation:
Answer:
w = (12p - 7) / 2
Step-by-step explanation:
p = (2w + 7) / 12
12p = 2w + 7
2w = 12p - 7
w = (12p - 7) / 2
Answer:
7.81mph
Step-by-step explanation:
Using the pythagoras theorem;
resultant r is expressed as;
r² = 5² + 6²
r² = 25 + 36
r² = 61
r =√61
r = 7.81mph
Hence the resultant speed is 7.81mph
