Nadia's download speed is 600 kbps and Jun's is 60 Mbps. How many times faster is Jun's speed than Nadia's?

• A. 1000x
• B. 2x
• C. 100x
• D. 10x

Answer: (A)

When comparing speeds with different units, convert to the same unit first. Nadia’s speed is 600 kilobits per second. Jun’s speed is 60 megabits per second, which equals 60,000 kilobits per second (since 1 megabit = 1000 kilobits). Now compare: 60,000 ÷ 600 = 100. So Jun’s speed is 100 times faster than Nadia’s. (You can also see this by converting Nadia to Mbps: 600 kbps = 0.6 Mbps, and 60 ÷ 0.6 = 100.)
