26 miles, 385 yards
= 26*5280 + 385*3 feet
= 138435 ft, (or 1.38435 x 10^5)
so half a a marathon = 692145 ft
number of strides in first half = 692145/5 = 138435 strides
number of strides in 2nd half = 692145/4.5 = appr 15382 strides
A runner tries to keep a consistent stride length in a marathon. But, the length will change during the race. A runner has a stride length of 5 feet for the first half of the race and a stride length of 4.5 feet for the second half.
1.)A marathon is 26 miles 385 yards long. That is about 1.4 × 105 feet. How many feet long is half a marathon?
2.)How many strides would it take to finish the first half of the marathon?
3.)How many strides would it take to finish the second half of the marathon?
im sorry im just so confused and im not really good with word problems.

Wait,Reiny I think your wrong. It said it is about 1.4 x 10 5 power,so it's 140,000 right?
Can you make this a little simpler to figure. This is just confusing.
sorry* figure out
i figured it out and 138435 divided by 2=692175
I got the same as Riney so I don't think its wrong
it is supposed to be in scientific notation so the other answer was correct
helpppppppppppppppppppppppp
You guys are all wrong, I would say the answer but the teacher took our papers but im being fr there is no way thats the answer (2021) ayy
