Sagot :

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:

[tex]speed=\frac{dis\tan ce}{time}[/tex]

• To find Lin's speed, we have:

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

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

• To find Noah's speed, we have:
