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
x = 7 1/2
x + 2 1/2 = 10
subtract 2 1/2 from both sides of the equation:
each crate has 1,092
64
12+4=16
16 x 4 = 64
