The answer is B 1,500 meters since 1 kilometer to meters is 1,000 and u add the 500
Answer: After one hour the distance will be 64 800 meters, after 1 minutes the distance will be 1080m, after 1 sec the distance will be 18m.
Explanation: Distance is speed multiplied by the time taken.
Using the standard formula V= d/t
Where v is a velocity,
D is a distance and
t is time.
We get use the formula to multiply the time taken by the velocity.
Answer:
#include <iostream>
#include <vector>
using namespace std;
int main() {
const int NUM_GUESSES = 3;
vector<int> userGuesses(NUM_GUESSES);
int i = 0;
int uGuess = 0;
for(i = 0; i <= userGuesses.size() - 1; i++){
cin >> uGuess;
userGuesses.at(i) = uGuess;
}
cout << endl;
return 0;
}
Explanation:
First inbuilt library were imported. Then inside the main( ) function, 3 was assigned to NUM_GUESSES meaning the user is to guess 3 numbers. Next, a vector was defined with a size of NUM_GUESSES.
Then a for-loop is use to receive user guess via cin and each guess is assigned to the vector.
All of the mineralls have a hardness rating less than what he used to perform the scratch test, with the exception of the quartz which had a higher hardness rating.
