Question

The energy released by metabolism of 1 average candy bar is 1 x 10^6 joules.

The energy needed for 1 hour of running for an adult is 4.5 x 10^6 joules. Use this information to determine how many average candy bars an adult would have to eat to supply the energy needed for seven hours of running.

Answer 1

Answer:32

Explanation:

Answer 2

Answer: 32

Explanation:

Given: The energy needed for 1 hour of running for an adult
`=4.5*10^6\ joules.`

Therefore. the energy needed for seven hours of running=
`=7*4.5*10^6\ joules.=31.5*10^6\ joules`

Since, he energy released by metabolism of 1 average candy bar
`=1*10^6\ joules.`

Therefore, the number of candy bars an adult need to eat to supply the energy needed for seven hours of running.=
`(31.5*10^6)/(1*10^6)=31.5\approx32`

Hence, the adult need to eat 32 candies to supply the energy needed for seven hours of running.
