Answer:
This rate in kilometers per hour is: 36 kilometers per hour. Also, the cyclist will travel 144 km in 4 hours.
Step-by-step explanation:
In order to find the rate in kilometers per hour, you have to consider that 1 meter per second is equal to 3.6 kilometers per hour and you can use a rule of three with this information:
1 meter per second → 3.6 kilometers per hour
10 meters per second → x
x=(10*3.6)/1=36 kilometers per hour
Now, you can use the formula to calculate speed and solve for the distance:
speed=distance/time
36=distance/4
distance=36*4
distance=144 km
According to this, the answer is that this rate in kilometers per hour is: 36 kilometers per hour. Also, the cyclist will travel 144 km in 4 hours.
