The ratio of m to km is
10/16
5:8
So for every 5 miles there are 8 km
45/5 = 9
9 * 8 = 72
Let's Check the answer:
45/72
5:8
So, its correct. The answer is 72 km.
<u>Answer:</u>
Distance = 3r
<u>Step-by-step explanation:</u>
We are to write an algebraic expression and then simplify it for the given situation:
<em>The distance traveled by a train in three hours with a constant speed of r miles per hour.</em>
We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r
