Carla is going on a boat tour. The boat will travel a total distance of 70 kilometres during the 10-hour tour. If the boat travels at a constant speed during the tour, what distance in kilometres should the boat travel in 3 hours.

21 km I think

Step-by-step explanation:

If you do 70/10 then you get 7 km per hour. Then you do 7*3 and get 21 km in 3 hours

Hope this helps, though this is kinda late :]

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.

use google you idiot omg you're so annoying
