Lizbeth is on the track team for her school. She can run 140 yards in 35 seconds. How long would it take her to run 400 yards
To find out how long it would take Lizbeth to run 400 yards, we can set up a proportion:
140 yards / 35 seconds = 400 yards / x seconds
Cross multiplying, we get:
140 * x = 35 * 400
Simplifying:
140x = 14,000
Dividing both sides by 140, we get:
x = 100
Therefore, it would take Lizbeth 100 seconds to run 400 yards.
