Answer: The correct option is

(A) 118.25 miles.

Step-by-step explanation: Given that Jack drove at an average speed of 47.3 miles per hour for 2.5 hours.

We are to find the distance traveled by Jack.

The relation between distance (d), time (t) and speed (s) is given by

$s=\dfrac{d}{t}.$

For the given situation, we have

s = 47.3 miles per hour, t = 2.5 hours and d = ?

Therefore, we get

$s=\dfrac{d}{t}\\\\\Rightarrow 47.3=\dfrac{d}{2.5}\\\\\Rightarrow d=47.3\times2.5\\\\\Rightarrow d=118.25.$

Thus, the required distance covered by Jack is 118.25 miles.

Option (A) is CORRECT.

The sum of a number and 6% of itself is 42.4. find the number

kvasek [131]

Answer:

Step-by-step explanation:

6% of number = 6/100 × x = 6x/100 = 3x/50

Sum of the number and 6% of itself = 42.4

x + (3x/50) = 42.4

(50x+3x)/50 = 42.4

53x = 42.4 × 50

53x = 2120
