Sarah and Emily ran a 324m race. If Sarah ran it in 61.3 seconds and Emily ran it in 60.4 seconds, how much faster was Emily than Sarah? Round to the nearest hundredth and give your answer in meters per second.

Work Shown:

Distance = rate*time

rate = distance/time

For Sarah, she runs 324 m in 61.3 seconds. Her speed is:

rate = distance/time

rate = (324 m)/(61.3 sec)

rate = (324/61.3) meters per second

rate = 5.28548 meters per second approximately

Repeat the same set of steps for Emily

rate = distance/time

rate = (324 m)/(60.4 sec)

rate = (324/60.4) meters per second

rate = 5.36423 meters per second approximately

The last thing to do is subtract the results we got

5.36423 - 5.28548 = 0.07875

This then rounds to 0.08 meters per second when rounding to two decimal places.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
