Question

Sandra rode her bike 5 times as many miles as Barbara. If b, the distance Barbara rode, equals 3.4 miles, what is the correct expression and distance Sandra rode?

Answer 1

3.4 x 5 = 17 thats how you find it

Answer 2

Answer: the expression is:

s = 5*b = 5*3.4 miles = 17 miles

Explanation:

If we define s as the amount of miles that Sandra did and b as the amount of miles that Barbara did.

We know that:

s = 5*b

and we also know that b = 3.4 miles

so we can replace the value of b in the equation above, and find the equation that says the distance that Sandra rode:

s = 5*b = 5*3.4 miles = 17 miles
