Peter walks along Sunrise Boulevard daily. He starts walking at 07:00 from block 10 and walks to block 90 where he turns around and walks back to block 70, where he stops at 07:30. The blocks along the boulevard are numbered sequentially (1,2,3), and each block measures 30 meters. What is Peter's speed in meters per minute?
Select the correct option
A) 100 B) 180 C) 198 D) 216 E) 252
Total distance from 10 to 90 =80 + from 90 to 70 =20   So the dist is 100×30(per block dist)   Speed = 3000mts/30min =100m/min   100 is the answer
<result>A</result>
