The car's speed in feets per second is 79.2, Hence, it will cover a distance of 158.4 feets in 2 seconds.

Car's speed in miles per hour = 54 miles per hour

Recall :

  • 1 mile = 5280 feets
  • 1 hour = 3600 seconds

Car's rate in feet per second

  • 54 miles per hour = (54 × 5280 × 1/3600) feet per second = 79.2 feets per second.

  • Distance in 2 seconds :
  • Distance = speed × time
  • Distance = 79.2 × 2 = 158.4 feets

Therefore, the car will cover a distance of 158.4 feets in 2 seconds.

Tomtit [17]

Answer:

1 in = 2.54 cm

Part (a)

Answer: 8.268 in

Part (b)

Answer: 11.693 in

Part (c)

In SI units standard-sized paper is 21.0 cm by  29.7 cm, which is equivalent to 8.268 in by 11.693 in.

Answer: 8.268 in by 11.693 in.

Part (d)

U.S sized standard paper is 8.0 in by  11.0 in. Therefore the SI (internationally) sized paper is longer.

Part (e)

If the U.S> adopts the SI standard for letter-sized paper, both the width and length of standard paper will have to be increased. Therefore letter-sized paper will occupy a larger area and will be heavier if the thickness and density do not change.

The sample space of an experiment is the set that contains all possible outcomes.

In this problem:

   For the coin, there are 2 outcomes.

   For the dice, there are 6 outcomes.

The coin and the dice are independent, thus, there are 2 x 6 = 12 possible outcomes, which means that the correct option is:
