Jean is driving from Mayville to a county fair in Yorkville. After driving for two hours at an average speed of 70 kilometers per hour, she still has 80 kilometers left to travel. What is the distance between the two towns, in kilometers?
A. 220
B. 250
C. 260
D. 270
E. 280
Distance = (rate)(time)So in this case we have:
Distance = (70 kilometers per hour)(2 hours) = 140 kilometersIn other words, Jean has driven 140 kilometers so far.
If she still has 80 kilometers left to travel, then the total distance between the two towns = 140 + 80 = 220
Answer: A
