Answer: He run 7 high-speed intervals and 8 low-speed intervals.
Step-by-step explanation:
Let x = Number of high-speed intervals.
y= Number of low-speed intervals .
He runs high-speed intervals in 16 seconds, and low-speed intervals in 23 seconds, and he runs a combined total of 15 intervals in 4 minutes and 56 seconds.
4 min 56 sec = (4(60)+56) sec = 296 sec [ 1 minute = 60 seconds]
According to the question , we have the following linear equations :
![x+y=15\ ...(i)\\\\ 16x+23y=296\ ...(ii)](https://tex.z-dn.net/?f=x%2By%3D15%5C%20...%28i%29%5C%5C%5C%5C%2016x%2B23y%3D296%5C%20...%28ii%29)
Multiply (i)by 16 , we get
![16x+16y=240\ ...(iii)](https://tex.z-dn.net/?f=16x%2B16y%3D240%5C%20...%28iii%29)
Subtract (iii) from (ii)
![7y=56\\\\\Rightarrow\ y=8](https://tex.z-dn.net/?f=7y%3D56%5C%5C%5C%5C%5CRightarrow%5C%20y%3D8)
Put value of y in (i) , we get
![x+8=15\Rightarrow\ x=7](https://tex.z-dn.net/?f=x%2B8%3D15%5CRightarrow%5C%20x%3D7)
Hence, he run 7 high-speed intervals and 8 low-speed intervals.
