The speed limit through a city is 50 Km per hour. If Jason drives 25 km through the city in 20 mintutes, has he broken the law?
+486 If it's $25$ km in $20$ minutes, then it is $75$ km in $60$ minutes which is $1$ hour, so Jason drove at $75$ kmph, which is above the speed limit.
+486 By multiplying the minutes by 3, so you go three times the distance, so $25*3=75$ km
