Question

The work needs to be shown plz

Answer 1

After 4 hours Jessica caught up to him......

 

Mike travels 6 hours.... Jessica travels 4 hours...

they cover the same distance along the same route.....

Jessica is 25 km.hr faster

 

 distance = rate x time

 Mike distance = Jessica distance

 

6 * r = 4 * (r+25)

 

6r = 4r + 100

 

2r = 100

r=50

 

Mike : 50 km/hr x 6 hours = 300 km

Jessica: 75 km/hr x 4 hours = 300 km
