It takes you 3 hours to drive to a concert 135 miles away.

What's the question?

Step-by-step explanation:

x = time on h-ways, y = rest of the time.

Then x+y = 3 and 55x + 40y = 135. By direct substitution,

55x + 40(3-x) = 135, so that means it’s TRUE that it takes you 3 hours to drive to a concert 135 miles away.

Step-by-step explanation:

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
