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

Answer 1

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.
