It takes carl 45 minutes to drive to work using two roads. she drives 32 mph on a small road for 1/2 hour. then she drives 56 mph on a small road for 1/4 hour. how far does she travel for work?

The Total distance she travel fro work is 30 miles  .

Step-by-step explanation:

Given as :

the total time taken to cover distance = 45 minutes

Let The total distance cover = D miles

The distance cover at the speed of 32 mph = miles

The time taken to cover miles distance = hour

Distance = Speed × Time

∴   = 32 mph  ×   h

or, = 16 miles

Again ,

The distance cover at the speed of 56 mph = miles

The time taken to cover miles distance =   hour

∴   = 56 mph  ×   h

or, = 14 miles

So , The total distance she travel for work =    +  

Or, The total distance she travel for work = 16 miles + 14 miles = 30 miles

Hence The Total distance she travel fro work is 30 miles  . Answer
