Answer:

27.42 m/s

Explanation:

Data provided in the question:

Distance traveled on a straight track = 0.754 km

Time taken to cover while going = 25.0 s

Time taken for the return = 30.0 s

Now,

Total distance covered = 2 × 0.754

= 1.508 Km

= 1508 m

Total time taken = 25 + 30 = 55 s

Therefore,

The average velocity of the car = Total distance ÷ Total time

= 1508 ÷ 55

= 27.42 m/s

Luden [163]

Answer:

If Mo pays cash, the cost of the purchase will be $140.

If Mo uses the credit card and pays the full balance during the billing cycle, the cost of the purchase will be $135.80.

Explanation:

If Mo pays cash, it implies that she does not get the 3% discount she is entitled to, with the use of her credit card.  Therefore, she will bear the full cost.  However, if she uses the credit card, the discount is $4.20 ($1540 * 97%) and she will pay only $135.80 as the discounted price of the electronic reader.
