Given:

• For Lin:

Distance = 234 miles

Time = 2/5 of an hour

• For Noah:

Distance = 823 miles

Time = 4/3 of an hour

Let's determine who ran faster.

Let's find the time of each runner by multplying by 60.

Where:

60 minutes = 1 hour

To determine the speed of each of them, apply the formula:


speed=(dis\tan ce)/(time)

• To find Lin's speed, we have:


\text{ Lin's sp}eed=\frac{dis\tan ce}{\text{time}}=(234)/((2)/(5)\ast60)=(234)/(24)=9.75\text{ mph}

Therefore, Lin's speed is 9.75 miles per hour.

• To find Noah's speed, we have:
