Hudson and Knox are in a race. Hudson is running at a speed of 8.8 feet per second. Knox got a 30-foot head start and is running at a speed of 6.3 feet per second. How many seconds will it take until Hudson and Knox have run the same number of feet? Write the equation.

Respuesta :

Answer:

It will take 12 seconds to be at same distance

The equation is;

8.8x = 6.3x + 30

Step-by-step explanation:

Let the number of seconds it will take be x

Mathematically, distance = speed * time

At x-seconds , Hudson will be at a distance of 8.8 * x = 8.8x ft

At x seconds , Knox will be at a distance of 30 ft + (6.3 * x) = 6.3x + 30feet

So the time it will take them to be at the same distance can be calculated using the equation;

6.3x + 30 = 8.8x

8.8x - 6.3x = 30

2.5x = 30

x = 30/2.5

x = 12 seconds
