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

Options:

Correct Answer: 2 km

Solution:

Distance A runs = 8 km/h * 0.5 h = 4 km. Distance B runs = 10 km/h * 0.5 h = 5 km. A is 1 km behind.

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

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

Step 1: Understand the speeds of A and B. A jogs at 8 km/h and B jogs at 10 km/h.
Step 2: Convert the time A jogs into hours. A jogs for 30 minutes, which is 0.5 hours.
Step 3: Calculate the distance A runs using the formula: Distance = Speed × Time. For A, it is 8 km/h × 0.5 h = 4 km.
Step 4: Calculate the distance B runs for the same time. For B, it is 10 km/h × 0.5 h = 5 km.
Step 5: Compare the distances. A runs 4 km and B runs 5 km.
Step 6: Find out how far ahead B is compared to A. B is 5 km - 4 km = 1 km ahead of A.
