Annie rides her bicycle the 1.5 km to Ben’s house at an average speed of 12 km/h. Calculate the percentage increase that 12 km/h is on Annie’s walking speed of 3.75 km/h.
I just dont understand how to solve this can someone please help
The question is asking you to find how much more quicky Annie is traveling on a bike compared to walking. We simply divide her biking speed by her walking speed to get a factor: [tex]x = 12 \div 3.75 \\ x = 3.2[/tex]
Then we convert this to a percent: 320 percent.
We can say that Annie is traveling 320 percent faster on a bike compared to walking.
