<u>Collinear points</u>: Three points A, B and C are said to be collinear if they lie on the same straight line.
There points A, B and C will be collinear if AB + BC = AC as is clear from the adjoining figure.
In general, three points A, B and C are <u>collinear if the sum of the lengths of any two line segments among AB, BC and CA is equal to the length of the remaining line segment</u>, that is, either AB + BC = AC or AC +CB = AB or BA + AC = BC.
In other words,
<u>There points A, B and C are collinear if:</u>
(i) AB + BC = AC i.e.,
Or, (ii) AB + AC = BC i.e. ,
Or, AC + BC = AB i.e.,

Answer:
Average Speed is 65 km/hr
Step-by-step explanation:
To get the average speed, first we have to calculate the time spent in the round trip .
Speed= Distance/ time
So, Time= Distance/Speed
Time Outgoing= 300km/ 97km/hr
Time Outgoing=3.0927 hr
Time lunch break =1 hr
Time return= 300km/ 58km/hr
Time Outgoing=5.1724 hr
Total= 3.0927 hr+1 hr+5.1724 hr=9.2651
To get average speed, we have to divide all the distance by the time it took al the trip.
Average Speed= Distance/ time
Average Speed= 600km/9.2651 hr= 64,76 km/hr
Average Speed=64,76 km/hr ≅ 65km/hr
