Landon is driving at a constant speed of 55 miles per hour. At hat rate, how long will it take him to drive 275 miles?
Elza [17]

Answer:

5hours

Step-by-step explanation:

At constant speed, distance speed= distance/time taken

therefore, time will be obtained by the division of distance traveled by the speed.  

in this question the distance is provided but time is not hence time is calculated as follows. time= distance/time taken

                            =275miles/55miles/hour

                            = 5hours
