The sprinter runs at a speed of 480 m / min, and the boy rides a bicycle at a speed of 27 km / h. Which of them is moving with great speed?
To complete the tasks, we will use the ratios:
1 km = 100 m;
1 h = 60 min = 3600 s;
1. Let’s express the speeds in the same units:
27 km / h = (27 * 1000/60) m / min = 450 m / min;
480 m / min> 450 m / min.
Answer: The sprinter moves faster.
