A city bus travels 6 blocks east and 8 blocks north. Each block is 100 m long. If the bus travels this distance in 15 minutes, what is the average velocity of the bus (m/s)?

1.56 m/s

Explanation:

For East direction, the 6 blocks is equivalent to 6*100=600 m

For West direction, 8 blocks is equivalent to 8*100=800 m

Speed is given by s=d/t where s is speed, d is distance covered and t is time taken

Total distance is 600+800=1400m

Time taken is 15 mins, converted to seconds will be 15*60=900 s

Speed, s=1400/900=1.5555555555555 m/s rounded off as 1.56 m/s

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
