4days and 12hours
Explanation:
Given parameters:
Average speed = 15m/s
Distance = 1800 miles
Unknown:
Number of days = ?
Solution:
Speed is the rate of change of distance with time;
Speed = ![\frac{distance}{time}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%7D%7Btime%7D)
Since the unknown is number of days, it is a measure of time:
Time = ![\frac{distance }{speed}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20%7D%7Bspeed%7D)
The distance from California to Lansing is 1800miles. The journey takes the truck drivers to and fro. It is a two way trip;
Total distance = 1800 miles x 2 = 3600miles
We need to convert miles to meters since that is the unit we can conveniently work with;
1 mile = 1609.34m
3600 miles = 3600 x 1609.34
= 5793638m
Inputting the values in the equation:
Time =
= 386242.53s
Now we need to convert to day;
In a day, = 60 x 60 x 24 = 86,400s
1 day = 86400s
Therefore;
The number of days =
= 4.47days
This implies that it will take them 4 days and approximately 12 hours.
