Questions & Step-by-Step Solutions
Two cyclists start from the same point and ride in opposite directions at speeds of 12 km/h and 15 km/h. How far apart will they be after 2 hours?
Step 1: Identify the speeds of the two cyclists. One cyclist rides at 12 km/h and the other at 15 km/h.
Step 2: Since they are riding in opposite directions, we need to add their speeds together to find the relative speed. So, 12 km/h + 15 km/h = 27 km/h.
Step 3: Determine how long they will be riding. The problem states they ride for 2 hours.
Step 4: To find out how far apart they will be after 2 hours, multiply their relative speed by the time. So, 27 km/h * 2 hours = 54 km.
Step 5: Conclude that after 2 hours, the two cyclists will be 54 km apart.
