Terry usually rides his bike 15mph. If his riding speed is reduced by 3mph how far can he ride in 1.7 hours

20.4 Miles

Explanation:

If Terry's riding speed is reduced by 3mph, he would be riding at 12mph.

12*1.7 = 20.4 miles

(miles per hour literally means how many miles you can travel in an hour at your current speed)

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
