Answer: C) d= 8t
Step-by-step explanation:
The first step is to find the speed of Taylor's run using the time and distance given:
[tex]30 = 4x\\/4=/4\\x = 7.5[/tex]
The next step is to find the speed of a runner going less than 35 miles in one hour.
[tex]35 > 4x\\/4 > /4\\x= 8.75[/tex]
Therefore, the equation for a runner faster than Taylor but less than 35 miles in 4 hours would be between 7.5 < x < 8.75.
The only equation that fits this is C) d = 8t.
