Question: A jogs at a speed of 8 km/h and B jogs at 10 km/h. If they start together, how far apart will they be after 30 minutes?

Options:

Correct Answer: 2 km

Solution:

Distance covered by A in 0.5 hours = 8 km/h * 0.5 = 4 km. Distance covered by B = 10 km/h * 0.5 = 5 km. Difference = 5 km - 4 km = 1 km.

A jogs at a speed of 8 km/h and B jogs at 10 km/h. If they start together, how far apart will they be after 30 minutes?

A jogs at a speed of 8 km/h and B jogs at 10 km/h. If they start together, how far apart will they be after 30 minutes?

Step 1: Understand that A jogs at a speed of 8 km/h and B jogs at a speed of 10 km/h.
Step 2: Convert 30 minutes into hours. Since 30 minutes is half an hour, we write it as 0.5 hours.
Step 3: Calculate the distance A jogs in 0.5 hours. Use the formula: Distance = Speed × Time. So, Distance covered by A = 8 km/h × 0.5 hours = 4 km.
Step 4: Calculate the distance B jogs in 0.5 hours using the same formula. Distance covered by B = 10 km/h × 0.5 hours = 5 km.
Step 5: Find the difference in distance between A and B. Subtract the distance A jogged from the distance B jogged: 5 km - 4 km = 1 km.
Step 6: Conclude that after 30 minutes, A and B will be 1 km apart.
