Question 984474: How long would I be walking backwards for ten minutes if it took 68 hundreths of a second for 5 meters,
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
5 meters every 68 hundredths of a second.
10 minutes is equal to 10 * 60 = 600 seconds.
600 seconds divided by 68/100 is equal to 600 * 100 / 68 which is equal to 852.3529412 seconds
what this means is that 68/100 of a second divides into 10 minutes 882.3529412 times.
if you are traveling 5 meters every 68/100 of a second, then you will have traveled 5 * 882.3529412 = 4411.764706 meters in 10 minutes.

another way of looking at it is as follows:

you walk 5 meters in 68/100 of a second.
this means that you walk 7.352941176 meters in a second.
ten minutes is equal to 600 seconds.
600 * 7.352941176 = 4411.764706 meters.
same answer, as it should be.

to test the reasonableness of the answer, do the following:
if you walk 7.352941176 meters in a second, then:
68/100 * 7.352941176 = 5 meters in 68/100 of a second.

all the numbers check out except it is not likely that you could walk that fast whether you were going forwards or backwards.

the average person walks about 3 miles per hour, going forward.

that comes out to be about 20 minutes per mile.

that means about 1/2 mile every 10 minutes.

you're walking 2.73 miles in 10 minutes?

not likely.
