Question

9 h × (70 mi / h)

Explanation:

Step1: Cancel the unit 'h'

The 'h' (hour) in the numerator of the first term and the denominator of the second term can be canceled out. So we have \(9\times70\space \text{mi}\).

Step2: Calculate the product

\(9\times70 = 630\).

Answer:

\(630\space \text{mi}\)
