Question 1200695
.
1. Peter traveled 450 km in 5 hours what was his average speed in km
2. if he traveled at the same average speed how far could he expect to travel in 7 hours
3. if he traveled at the same average speed how long would it take himto travel 1080 km
~~~~~~~~~~~~~~~~~~~~


<pre>
(1)  Tho find the average speed, divide the distance by the time

         average speed = {{{450/5}}} = 90 km/h.



(2)  In 7 hours, the expected distance is 7*90 = 630 kilometers,

     the product of the time by the average speed.



(3)  the time to travel 1080 km is {{{1080/90}}} = 12 hours.

     To find the travel time, divide the distance by the average speed.

From this my post, MEMORIZE how to find any of basic participating values in Travel and Distance problems.


It is very basic knowledge : it will work in thousands other Travel and Distance problems.
