Question

How long will it take you to travel 20 miles on a bus that drives 60 miles/h?

Answer 1

Answer:

20 Minutes

Explanation:

Well we know Mph (Miles per hour) is distance over time : $\frac{distance}{time}$

R (rate) = 60

d (distance) = 20

t (time) = Unknown

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 R = $\frac{d}{t}$  

   ↓

60 = $\frac{20}{t}$

   ↓

 t = $\frac{20}{60}$

    ↓

 t = $\frac{1}{3}$  or 0.3333

So basically it would take one third of an hour. Lets change these units to minutes.

60 * 0.333333 = 20

So it would take you 20 minutes to drive 20 miles on a bus that drives 60 mph

Hope that helps
