Equations for the acceleration:
Step-by-step explanation:
The acceleration of a body is the rate of change in velocity of the body; it is given by
where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to v
The equation can be also written as
Therefore, these two equations can be used to find the acceleration.

the question in English
The route of a stage of a cycle tour is 213 km long and a cyclist covers 2/3 of the route in five hours.
a) How many kilometers are left to finish the stage?
b) If he continues with the same average speed, how much time does he have left to finish the stage?
Step 1
we know that
1) Total kilometers of a stage is
2) The cyclist covers of the route
so
the kilometers remaining to finish the stage is equal to
therefore
<u>the answer Part a) is </u>
Step 2
<u>Find the average speed of the cyclist</u>
we know that
the speed is equal to
we have
substitute
Step 3
<u>Find the time remaining to finish the stage</u>
we know that
Solve for the time
we have
substitute
therefore
<u>the answer Part b) is</u>
