Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!

Part 1: A motorist traveling at 17 m per s encounters a deer in the road 48 m ahead. If the maximum acceleration the vehicle's brakes are capable of is -5 m per s2 what is the maximum reaction time of the motorist that will allow her or him to avoid hitting the deer? Answer in units of s. Part 2: If his or her reaction time is 1.29353s, how fast will (s) he be traveling when(s)he reaches the deer? Answer in units of m per s.
I am doing a free-fall experiment for Physics and I need to make a velocity vs. time graph using the average value of the final velocity. Do you know how I would be able to find the values for the velocity vs. time graph? The average value of the final velocity is 6.21954 m/s. It is question #9.
