A giant tortoise can live 175 years in captivity. The gastrotrich, which is a small aquatic animal, has a life span of only 3 days (72 hours). If a gastrotrich died after 36 hours, a giant tortoise that lived 87.5 years would live proportionally the same because they both would have died halfway through their life-span. How long would a giant tortoise live if it lived proportionally the same as the gastrotrich that died after 50 hours?

1 answer

The gastro would have lived 50/72 times its normal life span. So, for the tortoise,

50/72 = x/175
x = 121.5 years
