A rocket enters the range of a radar system mid-flight. It is tracked at the radar station, where its altitude is plotted as a function of the time since its initialdetection as shown in the graph below Rocket Trajectory
1 2 3 4 5 6 7 8 9 10
Time minutes)
According to this model, how many minutes elapsed between the time the rocket was launched from the ground before and when it was detected by the radar system? Assume the rocket follows a parabolic trajectory
A4 minutes
B 6 minutes
C 8 minutes
D
2 minutes

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

y -5 = (-1/4)(x + 8)
