Answer:

D. 21/2

Step-by-step explanation:

We simply have to evaluate the first three terms based on the progression's formula:

t= 1,  the first term is 8, as we see:

8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{1-1} = 8 * 1 = 8

t=2, the second term is 2, as we see:

8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{2-1} = 8 * \frac{1}{4} = 2

t=3, the third term is 1/2, as we see:

8(\frac{1}{4})^{t-1} = 8(\frac{1}{4})^{3-1} = 8 * \frac{1}{16} = \frac{1}{2}

The sum of the first 3 terms is then: 8 + 2 + 1/2 = 10 1/2

Among the answer choices, D. 21/2, which is 10 1/2.

Tom travels along the M1 from Leicester to London which is a distance
Gemiola [76]

Tom did not break the 70mph speed limit of M1.

To know if Tom breaks the <em>speed limit </em>of the M1, we must first calculate Tom's speed and compare it to M1's speed limit.

Using the formula below,

  • s = d/t............... Equation 1

Where:

  • s = Tom's speed
  • d = distance from Leicester to London
  • t = time taken to travel from Leicester to London

From the question,

Given:

  • d = 143 miles
  • t = 8:25 to 10:15 = 2 hours 10 munites = (2+10/60) = (2+0.17)
  • t = 2.17 hours.

Substitute these values into equation 1

  • s = 143/2.17
  • s = 65.899 mph.

Hence, Since Tom's speed is less than the M1 speed limit, Tom did not break the 70mph speed limit of M1.
