Three athletes ran a 100-m race. If they traveled 100 m in 10 seconds what was their average speed?

The law of Physics that we all learned in fourth grade, simplified as:

Rate x Time = Distance

That’s pretty much the one.

Have a look at this chart of some record breaking 100m races. Sub 1 second times for 10m splits are routine.

I am fat (obese according to the charts), old (55), and not a very good runner. I was doing fartleks (Sprints) this am at the end of my training run - approximately 170m sprints - and I was hitting top speeds of 5:55 min / mile.

This works out to 2.2 seconds per 10 meters.Step-by-step explanation:

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
