Question

A cyclist rides her bike at a rate of 8 meters per second. What is this rate in kilometers per hour? How many kilometers will the cyclist travel in 5 hours? Do not round your answers

Answer 1

Alrighty....
So, there's how many seconds in a minute? 60.
There's 60 minutes in an hour.
How many meters are in a kilometer? 1000.
So, to start, let's find out how many meters she travels per minute.
8(60)=480
Now, how many per hour? 480(60)=28800
So, if she travels 28800 meters per hour, we still need to find kilometers.
28800/100=288
So 288 km per hour.
Now, 288(5)=1440. :)
