Answer:
The answer is 5 years
Step-by-step explanation:
You must do 85 cm ÷ 17 cm to find how many years in which the cliff will erode 85 centimeters and the answer is 5.
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
