The formula to find speed is distance divided by time or s = d / t. With this in mind, let's plug in some numbers into the equation.
Since they're asking for meters per second, multiply 60 seconds by 2 minutes:
60 * 2 = 120
Now add that to 56.35 (the amount of seconds we already know):
120 + 56.35 = 176.35
So, now that we know how many seconds they ran in total, divide the distance (1600) by the time (176.35):
1600/176.35 = 9.072866...
Round 9.072866... to the nearest hundredth, which is 9.07. And there's you're answer! They ran about 9.07 meters per second :)
Answer is D.x=9
5x+3+6x+5+8x+1=180
now solve for 'x'
Hope this help
