Question

A bird uses about 0.01 Cal to fly 1000 m. In average, the bird eats 40 g of food daily (providing in average 150 cal/g) which is converted to useful energy with an efficiency of 15%. Determine the maximum distance that the bird can fly each day.

Select one:

a.) 22 km c.) 90 km

b.) 60 km d.) 600 km

A bird uses about 0.01 Cal to fly 1000 m. In average, the bird eats 40 g of food daily (providing in average 150 cal/g) which is converted to useful energy with an efficiency of 15%. Determine the maximum distance that the bird can fly each dav Select one: O a. 22 km O b. 60 km c. 90 km d. 600 km

Explanation / Answer

Solution:

Energy consumed by the bird daily = 40 * 150 = 6000 cal

Given 15 % of energy is useful so 15 % of 6000 = 900 cal is used to fly

=> 0.01 cal to fly 1000m

=> 1 cal to fly 100000 m

=> 900 cal can be used to fly = 90000000 m = 90000 km

I think options are wrong or question has some wrong value.

but you can go with 90 km

please comment for queries.

thanks.
