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.

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
