The average speed of a car during 5 hours is 50 miles per hour. What is the total distance traveled by the car?

Mathematics

Paraphin [41]3 years ago

Answer:

250 miles

Step-by-step explanation:

So we know that the time (t) equals 5 hours and that the rate (r) equals 50 mph. So knowing that, we can use the formula t*r=distance. We plug in the numbers and we get 250 miles.

Another way to think about this is, since we go 5 hours and 50 miles per hour, every hour we go 50 miles and we do that for 5 hours, so we go 50, 100, 150, 200, 250.

blondinia [14]

Answer:

0.03333

Step-by-step explanation:

Given that there are three machines. All of the machines can produce 1000 pins at a time.

Chance for any machine is thus equaly likely = 1/3

The rate of producing a faulty pin from Machine 1 be 10%, from Machine 2 be 20% andfrom Machine3 be 5%.

Machine             I                     II              III                  total

Faulty              0.10                0.20        0.05

Prob                0.3333           0.3333    0.3334             1

Faulty*prob    0.03333         0.06666  0.16665         0.26664

Thus probability  that a produced pin will be faulty and it will be from the firstmachine

= 0.03333
