Acar travels down the highway at speeds between 50 miles per hour and 65 miles per hour. if the car travels for 4 hours, write an expression that represents the distance, d, the car has travelled.

In making an expression of a solution that corresponds data or given information is easy because the given can be use to answer it. So in your problem, Let the Variable A be the distance travelled by the car in one hour and multiply it by 4 equals to the Variable D. So the expression would be 200 less than or equal to D less than equal to 260

Agc and bgd are vertical angles
