Question

Joseph cycled a distance of 4 miles in 45 minutes. What is the unit rate at which Joseph was cycling?

Answer 1

Because
rate = distance/time
r = $\frac{4 miles}{45 minutes}$
so it would be
r = $\frac{4}{45}$ miles per minute

Or if it was miles per hour:
$\frac{4}{45} = \frac{x}{60}$
Cross multiplication gives us
45x = 240
$\frac{16}{3}$ mph
