A cyclist rides her bike at a speed of 12 meters per second. What is this speed in kilometers per hour? How many kilometers will the cyclist travel in 2 hours? Do not round your answers.

1) 43.2 kilometres per hour

2) 86.4 kilometres

Step-by-step explanation:

To convert m/s to km/hr ...;

you multiply your speed in m/s by 3600/1000

12m/s in km/hr

; 12 * 3600/1000

Hence the speed = 43.2 kilometres per hour

Kilometres travelled in 2hrs

; Distance = Speed * Time

; Distance = 43.2 * 2

; the distance travelled = 86.4 km/hr
