i dont know the answer, but i reccommend using mathpapa.com as they give you the answer PLUS the explaination.
Step-by-step explanation:
time = 2 hours
distance travelled(d) = 124 miles
so
speed = d/t
= 124/2
= 62 miles per hour
Therefore, the speed of car is 62 miles per hour.
Answer:
61,01%
Step-by-step explanation:
We must consider that her total energy intake is the addition of the energy given by the carbohydrates, fats and proteins she takes.
1g of carbohydrates contains 4kcal
1g of proteins contains 4kcal
1g of fat contains 9 kcal.
That is: 243 g of carbohidrates is equal to 972 kcal; 41g of fat is equal to 369 kcal and 63 g of proteins is equal to 252 kcal.
If we sum up all the calories she intakes in one day, the result is= 972kcal+369kcal+252kcal=1593kcal.
Now, we make a rule of 3: If 1593kcal is the 100% of the intake, then 972kcal = 972kcal*100%/1593kcal = 61,01%
Answer:
