It's hard to understand what exactly you're asking.

If you're asking how many meters per second he's flying, the answer is 51 meters per second.

If you're asking how much longer till he reaches Lois, the answer is around 26 seconds.

If you're asking how far away he was BEFORE he started flying, the answer is 2,100 meters.

If you're asking about the total amount of time he traveled from beginning to end, the answer is around 41 seconds.

I'm like 97% sure these are correct.

Nevertheless, I hope this helped! :)

Solve for x 26=3x+2x-9
umka2103 [35]
Combine like terms on the right side:

3x + 2x = 5x
26 = 5x - 9

Add 9 to both sides:

35 = 5x

Divide both sides by 5 to get x by itself:

x = 7

The value of x is 7.

Corey and Devante both leave the park at the same time but in opposite directions if Corry travels 30 mph and Devonta travels 22
telo118 [61]

Answer:

  2 hours 1 minute 9.23 seconds

Step-by-step explanation:

Since they are traveling in opposite directions, their separation speed is the sum of the magnitudes of their speeds: 30 +22 = 52 mph.

The time is related to speed and distance by ...

  time = distance / speed

  = (105 mi)/(52 mi/h = 2 1/52 h ≈ 2 h 1 min 9.23 sec

It will take a little over 2 hours before they are 105 miles apart.
