Answer:
C
Step-by-step explanation:
<h3>
Answer: 4900 mph</h3>
Work Shown:
30 min = 30/60 = 0.5 hours
distance = rate*time
rate = distance/time
rate = (2450 miles)/(0.5 hours)
rate = (2450/0.5) mph
rate = 4900 mph
For the sake of comparison, a typical commercial passenger jet can reach max speeds of about 600 mph.
(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.
Answer:
