The average speed at which Lixin is walking to the mall is 5.54 km/h

Step-by-step explanation:

Distance of the mall from Lixin’s house = 628 m = 628/1000 = 0.628 km

Time taken by Lixin to cover this distance = 6.8 mins = 6.8 / 60 = 0.1133 h

Thus, the speed at which Lixin is walking, speed = distance / time

                                                                                  = 0.628 / 0.1133

                                               = 5.54 km / h

Thus, Lixin is walking from her house to the mall at a speed of 5.54 km/h
