When we add the two equations vertically. we get 5x=10 (3x+2x and 4+6, the y's cancel each other out) ∴x=2. Substitute this into any of the equations and we get y=2

so, x=2 and y=2

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,

$320 = R \times 5.0\\\\R = \frac{320}{5}\\\\R = 64$

Thus the speed of car is 64 kilometer per hour

We cannot round the answer to nearest tenth, since answer is not in decimal
