Asked by Tobi

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?

4.) How many strides would it take the runner to complete marathon? Express your answer in both scientific notation and standard notation.

Don't know what the big deal is with scientific notation, the numbers are relatively small, no need for SN.
