Question

night crawler worms live about 6 year in the wild and grow up yo 14 inches l9ng. these worm burrow down in thr day about 6.5 feet and emerge at night to feed.

Part a: given this average burrowing rate, how many yards does a night crawler burrow per week? Round to the nearest yard

Part b: given its average lifespan, how many miles does a night crawler butrow in its lifetime? Round to the nearest tenth of a mile​

Answer 1

Based on the information given, the night crawler worm burrows 15.17 yards. This prompt requires a lot of conversion between Units of Length.

Part A: What is the calculation justifying the above solution?

Given that Night Crawler Worms burrow 6.5 feet per day.

Yards burrowed per week = 6.5 x 7 x 0.333333

Where 1 foot = 0.333333

Hence,

6.5 x 7 =45.5

45.5 x 0.333333

$\approx$ 15.17 yards

Part B: Given its average lifespan, how many miles does a night crawler burrow in its lifetime?

We have been given:

Night Crawler Worms live up to 6 years.

If they burrow 6.5 feet per day

Hence, Total miles burrowed in a life time = 365 x 6 x 6.5 x 0.000189394

Where 1 foot = 0.000189394

Recall that there are 365 days in a year.

Hence,

Total miles burrowed in a life time = 365 x 6 x 6.5 x 0.000189394

= 2.69602359

$\approx$ 3 miles
