Jason runs around a 400-meter track for training. during the month of september he ran around the track 520 times. how many kilometers did he run in september? a certain antacid tablet contains 500 mg of calcium carbonate. if the doctor warns jill not to take over 8 g per 24-hour period, how many tablets can she take in a day?

208 km

16 tablets per day

Step-by-step explanation:

Given:

Length of training track run by Jason = 400 m

Number of times Jason ran on the track = 520

Therefore,

The total length covered by Jason = 520 × 400 = 208,000 m

now,

1 Km = 1000 m

thus,

208,000 m =

or

= 208 km

b) Amount of calcium carbonate in a tablet = 500 mg = 0.5 g

Maximum amount of calcium carbonate that can be taken = 8 g

hence,

the maximum number of tablets that she can take

=

=

= 16 tablets per day

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
