Question

It takes Sharon 36 minutes to travel to her school which is 3.5 miles away. If she traveled at the same rate of speed, how long will it take her to get to her friends house 4.7 miles away? (Round your answer to the nearest minute.)

Answer 1

Use proportions here:

$\frac{3.5}{36} = \frac{4.7}{x}$

Cross-multiply.

3.5x = 169.2

x = 48 minutes.
