Answer:
Jeremiah travels at 26.667 mi/hr and Ermias travels at 18.667 mi/hr.
Step-by-step explanation:
Say Ermias' speed is 's' and Jeremiah's is 'v'
distance = rate * time
distance = ( v * time) + ( s * time)
v = s + 8
240mi = ( (s+8) * 8 ) + ( s + 8)
240 = (8s +64) + s + 8
240 = 9s + 72
240 - 72 = 9 s
168 = 9 s
18.6666667 = s
v = 18.6666667 + 8
v = 26.6666667

Answer:
Minimum - 8.1 inches
Maximum - 8.35 inches
Step-by-step explanation:
The specifications for manufacturing a steel rod stipulate that the length must be 8.225 ± 0.125 inches.
This means that the minimum length must not be 0.125 inches less than 8.225 inches and the maximum length must not be 0.125 inches greater than 8.225 inches.
The minimum length is therefore:
8.225 - 0.125 = 8.1 inches
The maximum length is therefore:
8.225 + 0.125 = 8.35 inches
