Distance

Jason took 40 min to drive from East Mall to West Mall. He drove at an average

speed of 60 km/h for the first 25 min. He then increased his speed by 12 km/h for

the remaining journey. What was the distance between the two malls?

Answer: 28 km

Step-by-step explanation: For the first 25 minutes, he drove 60 km/h. Since there is 60 minutes in an hour, we know that he drove 25 km. The rest of the journey is 15 minutes. 15 minutes is 1/4 of an hour, so get 1/4 of 12 km/h. This would be 3 km. Add 25 km and 3 km. The distance between the 2 malls is 28 km.
