The tourists went in the first hour with a speed of 3.5km/h to the bus station, realizing that they would arrive 1 hour late at the bus station by moving so, they increased their speed by 1,5km/h and arrived now 30 min earlier. How long is the distance they walked?

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.
