A car travelled a distance of D =320 kilometers for T =5.0 hours at a constant rate use the formula D =R. T To find the speed (R) of the car in km per hour Round your answer to the nearest tenth do not include the units in your answer

Answer :

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
