Step-by-step explanation:
just look at the objects !
they are completely regular, and each arm can cover every other other arm.
so,
15A needs 1/3 of a full rotation.
15B needs 1/2 of a full rotation.
15C needs 1/4 of a full rotation.
15D needs (can you guess ?) ... 1/6 of a full rotation.
Answer
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
3 miles ÷ 2
2 hours ÷ 2
=
1.5 miles
1 hour
=
1.5 miles
hour
= 1.5 miles per hour
Answer:
<h2>
29.17m/s²</h2>
Step-by-step explanation:
Acceleration is defined as the change in velocity of a body with respect to time.
Acceleration = velocity/time
Given velocity of the space shuttle = 525m/s and time = 18.0seconds
Its average acceleration = 525/18
Its average acceleration (in m/s²) = 29.17m/s²
