One lap of a running track measures 255 m. To run 10.0 km, how many laps should you run?

Answer 1

Zoe Adams

#(10,000m)/(255m) = 39.22# laps is exactly 10 Km.

If complete laps are to be run, 40 laps are needed..

To find the number of times 255m can "fit into" 10km, we must divide 10.0km by 255m.

Since the units are not the same, we cannot divide until they are.

Either use: #10.0km xx1000 = 10,000m#

OR: #" 255m "div 1000 = 0.255Km#

#(10,000)/255 = 39.22 rArr 40 # laps.

If complete laps have to be run, 40 laps will be 10 Km.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
