If 2 cars traveling towards one another are 100 miles apart and car A is traveling at 55 miles/hour, while car B is traveling at 60 miles/hour, which time is closest to when they meet if it is 2:00 pm now?

Answers

Answer:

Explanation:

The time when they meet is t in hours

The general formula for both cars  is d = r*t

t is unknown

r1 = 55 mph

r2 = 60 mph

60 mph * t  + 55 mph*t = 100 miles

t * (60 mph + 55 mph) = 100 miles

t * 115 = 100 miles

t = 100 miles / 115 mph

t = 0.8696 hours

1 hour has 60 minutes

0.8696 hour = x

x = 0.8696 hours * 60

x = 52 minutes  and 10 seconds

They will meet at 2:52:10

Why are generic pharmaceuticals significantly cheaper than name brand ones?

NEED HELP ASAP

Answers

Answer:

Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness.

Generic pharmaceuticals are significantly cheaper than name brand ones because generic pharmaceuticals are not protected by patent law, so the lack of barriers to entry and increased competition keep prices down.

Also, the makers of generic drugs do not have to cover the cost of developing and marketing a new product.
