Ron walks along Sunrise Boulevard daily. He starts walking at 7;00 from block 10 and walk to block 90 where he turns around and walks back to block 70, where he stops at 7:20. The blocks along boulevard are numbered sequentially (1, 2, 3), and each block measures 36 meters. What is Ron's speed in meters per minutes?
A. 108
B. 180
C. 198
D. 216
E. 252
The OA is B.
We know that,
$$Speed=\frac{Dist}{Time}$$
The total distance covered by him is, 36(80 + 20) = 3600 meters.
The total time is 20 minutes, then his speed in meters per minutes will be
$$Speed=\frac{3600}{20}=180$$
Experts, any suggestion about this PS question? Thanks in advance.
