10​

Answer 1

Answer:

Explanation:

Given:

Distance moved =100m=100/1000=0.1km

time=15min=15/60=0.25hr

Formula:

Average Speed= Total Distance/Total Time                           

                         = 0.1/0.25=0.4 Km/hr

Therefore the average speed of tortoise is 0.4km/hr

Answer 2

av speed = 100m/15min= 20m/3min

20m = 20km×1/1000 =1/50 km

3 min = 3hours × 1/60= 1/20 h

av speed = 20/50 = 2/5 km per hour
