Answer:
The expression for the total distance between the car and the landmark in terms of the number of hours spent driving is given as follows;
1.2 = 65 × t
Where t = 1.2/65 = 0.0185 h = 66.46 seconds
Step-by-step explanation:
The parameters given are;
Distance, d between car and landmark = 1.2 miles
Speed of car = 65 miles/hr
Distance between truck and landmark = 0.7 miles
Speed of car = 55 miles/hr
The expression for the total distance between the car and the landmark as a function of time t is given as follows;
Distance, d = Speed, v × Time, t
Therefore, the expression for the total distance between the car and the landmark in terms of the number of hours spent driving is given as follows;
1.2 = 65 × t
Where t = 1.2/65 = 0.0185 h = 66.46 seconds.
