The two cars (a and b) will be 800 km apart after 10 hours.
What is the average speed of a car?
The average speed of a car is the total distance traveled by a car within a specific period of covering such distance.
From the given information:
- If the speed of car A (v_a) = 30 km/hr; and
- The speed of car B (v_b) = 50 km/hr
The distance between both cars will be the hours they will meet:
i.e.
[tex]\mathbf{(v_a \times t)+(v_b\times t)= 800 \ km}[/tex]
[tex]\mathbf{(30 \times t)+(50\times t)= 800 \ km}[/tex]
30t + 50t = 800
80t = 800
t = 800/80 hrs
t = 10 hrs
