4 
km
Step-by-step explanation:
To find how much farther Hallie biked after lunch compared to the amount she biked before lunch, we can subtract the amounts:
6 
However, we can only subtract fractions that have the same denominator, so we need to convert 
to a fraction with a denominator of 8:
Now, we can't subtract 2 from 8, so we need to 'borrow' from the 6 to make the fraction larger:
Now subtract: 
120 grams half life at 45 days would be 60 then half life of 60 in another 45 days (90 total) should be 30 grams
Answer:
The acceleration of the car will be 400 m/s².
Step-by-step explanation:
The acceleration of the car can be found using Newton second law:
Where:
F: is the net force = 200 N
m: is the mass = 500 g
a: is the acceleration =?
Then, the acceleration will be:
Therefore, the acceleration of the car will be 400 m/s².
