Explanation of Solution

Given:

The given quantity is “the distance that a car travels in 45 min”.

s is the speed of the car (in mile/hr.).

Concept used:

Distance is the product of speed and time is given by d=st .

Calculation:

According to question,

t=45min=4560hrs=34hrs

Therefore, distance covered by the car is

d=s×34miles/hrs=0.75smiles/hrs .

Hence,distance covered by the car is d=0.75smiles/hrs .
