Answer:When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.
Since 1000m=1km, we have 100000m/hr for the car. 75/100000 gets the fraction of how long in an hour it would take. Since there are 60*60=3600 seconds in an hour, we multiply 75/100000 by 3600 to get 2.7 seconds
