The motorcycle traveled for 3 hours at a speed of 60 kph, at which speed the motorcyclist will ride in 2 hours if the entire distance is 360 km.

To solve the problem, we will use the formula for calculating the distance:
S = V * t,
where S is the distance,
V is the speed of the motorcyclist,
t – time of movement of the motorcyclist.
Let’s determine the distance traveled by a motorcyclist at a speed of 60 km / h and a travel time of 3 hours:
S = 60 km / h * 3 h = 180 km.
Since all distances are 360 ​​km, and the motorcyclist traveled 180 km, the remaining distance is:
360 km – 180 km = 180 km.
Let’s determine the required speed of a motorcyclist to overcome the remaining 180 km in 2 hours, expressing it from the formula for calculating the distance:
S = V * t, so V = S / t.
Substitute the values ​​into the formula and find the speed of the motorcyclist:
V = 180 km / 2 h = 90 km / h.
Answer: to overcome the remaining 180 km in 2 hours, the motorcyclist needs to move at a speed of 90 km / h.
