The speed of car is 64 kilometer per hour
Solution:
Given that car travelled a distance of D = 320 km for T = 5.0 hours
To find: speed (R) of the car in km per hour
Formula given:
D = R. T
where "D" is the distance
"R" is the speed of car
"T" is the time taken
Substituting the given values in above formula we get,
[tex]320 = R \times 5.0\\\\R = \frac{320}{5}\\\\R = 64[/tex]
Thus the speed of car is 64 kilometer per hour
We cannot round the answer to nearest tenth, since answer is not in decimal
