A highway crew has the same stretch of highway to repair. but they must do it in 2.5 day. how many miles will they have to repair each day to finish the job on time.

Solution

Let the length of highway be x miles

Work must be completed in 2.5 day

Hence the number of miles they have to repair each day = Total distance/Total time = x/2.5 = 0.4x miles

Hence the crew must repair 0.4x miles of the distance in order to finish their work on time where x represents the length of the complete highway to repair
