If the car went 30 km west in 25 min. and then 40 km south in 35 min., what would be its average speed?

Average speed  =  (distance covered) / (time to cover the distance)

                          =  (30km + 40 km)  /  (25min + 35min)

                          =        (70 km)  /  (60 min)

                          =             70 km/hour

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
