The speed of an object is the <u>relationship</u> between the <em>distance</em> covered by the object and the<em> time taken</em>. Thus, the <em>average speed</em> of the other car is 30 mph.
The speed of an object is the <u>relationship</u> between the <em>distance</em> covered by the object and the<em> time taken</em>. The <em>expression</em> for <u>speed</u> is given as;
speed =
⇒ distance = speed x time taken
In the given question, the <u>distance</u> of the first car after 2 hours can be determined as:
distance = 80 mph x 2 h
= 160 miles
The <u>distance</u> covered by the <em>first</em> car after 2 hours is 160 miles.
Thus, since the <em>total distance</em> between the two cars after 2 hours is 220 miles, then;
<u>distance</u> covered by the <em>second</em> car = 220 miles - 160 miles
= 60 miles
The <u>distance</u> covered by the second car is 60 miles.
So that the <em>average speed</em> of the other car is;
speed =
= 30 mph
The average speed is 30 miles per hour (mph).
