Gabby drove 124 miles in 150 minutes. find gabby's speed in kilometers per hour. ( for test tmrrw plz 15 ! )

First, you need to convert the minutes into hours, to do this you divide the minutes by 60 (the amount of minutes in an hour). Once you've gotten the value (which is 2.5), you divide that by the amount of miles drove, then you get the unit rate, or in other words      the kilometers per hour, which equals 49.6 km/h
