Question

Brandon can reach an average speed of 30 km/hr on his bicycle. How long will it take him to cycle 120 kilometers?

A) 4 hours
B) 3 hours
C) 2 hours
D) 1 hour

Answer 1

To calculate the time it will take Brandon to cycle 120 kilometers at an average speed of 30 km/hr, divide the distance by speed, resulting in 4 hours (Answer A).

Step-by-step explanation:

When determining how long it will take Brandon to cycle 120 kilometers at an average speed of 30 km/hr, we use the formula time = distance/speed. Plugging the values into the formula, we get time = 120 km / 30 km/hr, calculating out to 4 hours. Therefore, the correct answer is A) 4 hours.

This question is a basic application of the concept of average speed, which is crucial to solving problems involving distance, time, and speed relationships. This fundamental principle is taught within middle school mathematics and is an integral part of understanding motion.
