16 divided by 0.64 (the percentage as a decimal) = 25
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.

Answer:
Extraneous Solutions An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation. Example 1: Solve for x, 1 x − 2 + 1 x + 2 = 4 (x − 2) (x + 2).
Answer:
6
Step-by-step explanation:
the hypotenuse should be 3√2*√2=6
Answer:
[-2, ∞]
Step-by-step explanation:
15 - √(x+2)
domain is any value as long as (x+2) is not-negative, since √ of a negative number has no Real solution.
x+2 ≥ 0 ⇒ x ≥ -2
