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.

Answers

Answer: 32

Step-by-step 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.
