Question

Emily is entering a bicycle race for charity. Her mother pledges $0.30 for every 0.5 mile she

bikes. If Emily bikes 10 miles, how much will her mother donate?
Her mother will donate $

Answer 1

We know that her mother will donate 0.30 for every 0.5 miles she bikes. We can convert this to one mile, which is 0.60 cents per mile. We can now multiply by ten. This will gives us $6.

Another way to solve this is divide 10 by 0.5. This gives us 20, and if we multiply 20 by 0.30 we get $6.

Answer 2

The mother will donate $5
