The speed of the cyclist is 12.5 km / h, and the speed of the pedestrian is 6.2 km / h less. At what speed do they approach each other if they are moving towards each other?
1) Determine the speed of the pedestrian.
Since it is 6.2 km / h less than the speed of the cyclist, it is necessary to subtract the indicated difference from the speed of the cyclist.
We get:
12.5 – 6.2 = 6.3 km / h.
2) Find the speed of convergence.
To do this, add the speed of the cyclist to the speed of the pedestrian
As a result, it will be:
12.5 + 6.3 = 18.8 km / h.
Answer: The cyclist and the pedestrian approach each other at a speed of 18.8 km / h.
