a = 4.4 m/s^2 This is an acceleration and is positive.
vi = 10.2 m/s
t = 4.2 seconds
vf = ????? The cruising speed in this case is vf.
Formula
a = (vf - vi)/t Notice the 3 givens and what you seek determine the formula
Solve
4.4 m/s^2 = (vf - 10.2)/4.2 Multiply both sides by 4.2
4.4 * 4.2 = vf - 10.2
18.48 = vf - 10.2 Add 10.2 to both sides
18.48 + 10.2 = vf 8.28 is the second best answer.
28.68 = vf This is your cruising speed.
C <<<< Answer
1 minute = 60 seconds
You need to multiply the speed in m/s with 60 seconds and you will get the speed in meters/minute.
Covnersion factor is 60 seconds.
Solution would be : 20,1m/s * 60s = 1206meters/min

Answer:
Step-by-step explanation:
Angles 3 and 6 are consecutive interior angles
<u>As per definition, consecutive internal angles add to 180°</u>
- m∠3 = 67° ⇒
- m∠6 = 180° - 67° = 113°
