Sagot :
The car will require 2304MJ to convey four people over a distance of 640km.
Data;
- Consumption per kilometer = 3.6MJ
- distance travelled = 400miles
Conversion of Miles to Kilometer
To solve this problem, we have to convert the distance travelled from miles to kilometer.
[tex]1mi=1.6km[/tex]
Let's convert 400miles to kilometer
[tex]1mi=1.6km\\400mi=x km\\x = \frac{400*1.6}{1}\\ x = 640km[/tex]
But we were told that the car requires 3.6MJ per kilometer, how much MJ will it take to cover 640km.
[tex]1km=3.6MJ\\640km= x MJ\\x = 640*3.6\\x = 2304MJ[/tex]
From the calculations above, the car will require 2304MJ to convey four people over a distance of 640km.
