FEEDBACK

Speed of Jennifer on Sunday mi/hr

Step-by-step explanation:

Let speed of Jennifer on Saturday be x mi/hr

On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend.

Distance travelled by Jennifer on Saturday = Speed × Time miles

Speed of Jennifer on Sunday = mi/hr

On Sunday evening, due to  heavy traffic, it took Jennifer 4 hours to return home.

Distance travelled by Jennifer on Sunday = Speed × Time miles

As distance is obviously same on both Saturday and Sunday,

Therefore,

Speed of Jennifer on Sunday =  mi/hr
