To find out how long it would take for Danni to complete a race that is 600 meters at the same rate, we can use the formula:
speed = distance/time
We know the distance (600 meters) and the speed (400 meters/5 seconds), so we can rearrange the formula to solve for time:
time = distance/speed
time = 600 meters / (400 meters/5 seconds)
Simplifying the expression inside the parentheses:
time = 600 meters / (80 meters/second)
Dividing 600 by 80:
time = 7.5 seconds
Therefore, Danni will be able to complete the 600-meter race in 7.5 seconds. So the correct answer is 7.5 seconds.
