A car is traveling at a speed of 55 miles per hour What is the approximate speed of the car in meters per second? (Use 1 mile = 1,609 meters) A 25 meters per second
B 30 meters per second
C 123 meters per second
D 246 meters per second

The answer is A

Step-by-step explanation:

55mi x   1hr    x   1min  x 1.61*103m = 24.6m/s

1 hr     60min      60sec        1mi

And then you round 24.6 to 25 so your answer is A

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
