3. From the beginning of a trail, Claire hiked 4 3/8 to the lake. Then she hiked 2 5/8 to the nature center. Is 5 miles, 6 miles, or 7 miles the most reasonable estimate for how far Claire hiked altogether?​

7 miles

Step-by-step explanation:

Add up the total time she hiked:

4 3/8 + 2 5/8 = 7

in total she walked 7 miles

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.
