eelina walked faster than denis

Answer 2

Answer:

Dennis walked faster by 0.75 miles/hr

Step-by-step explanation:

a)Selina's speed

speed= distance

                 time

          = 2.5 miles       =  3.75 miles/hr = the slower

               2/3 hrs

b) Dennis' speed

speed =  distance

                  time

           =  6.75 miles        = 4.5 miles/hr  = the faster    

                   1.5 hrs

difference in speed:

faster - slower

4.5 - 3.75

=0.75 miles/hr
