Answer:
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

Answer:
B. 7.6 km/s
Explanation:
Given:
Speed of the satellite orbiting Earth is, 
In order to convert the speed from miles/hour to km/s, we need to convert miles to km and hour to seconds.
The conversion factors are:
0.62 miles = 1 km
∴ 1 mile = 
1 hour = 3600 s
Now, 17000 miles/hour can be rewritten as:
Therefore, the speed in km/s is 7.6 km/s.
