In an 18-meter race between a tortoise and a hare, the tortoise leaves 23 minutes before the hare. The hare, by running at an av
erage speed of 0.5 meter per hour fast than the tortoise, crosses the finish line 1 minute before the tortoise. What are the average speeds of the tortoise and the hare?
We know that: time=distance/speed if the tortoise speed is x m/min, then since 0.5 m/hr=1/120 m/min 18/x=23+18/(x+1/120) solving for x we get: x=0.08 m/min speed of hare is: (0.08+1/120)=0.088 m/min
