Question

Bob drove from home to work at 60 mph. after work the traffic was? heavier, and he drove home at 50 mph. his driving time to and from work was 1 hour and 28 minutes. how far does he live from his? job?

Answer 1

To answer this item, we let x be the distance separating Bob's home and workplace. Time is calculated by dividing the distance by the speed. It should be noted that every hour contains 60 minutes. 
         
                                x/60 + x/50 = 1 + 28/60
The value of x from the equation is 40. Thus, the distance from Bob's home to workplace is 40 miles.
