225 mins long will a bus take to travel 150 km at an average speed of 40 km h
Since the average speed is 40km/h it means
40 km can be travelled by it in 1 hour
1 km can be travelled by it in 1/40 hour
So 150km can be travelled by it in 150/40 hours or 225 mins.
By formula time=distance/speed=150/40=3.75hours
Speed = Distance/Time – This tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance. Time = Distance / Speed, as the speed increases the time taken will decrease and vice versa.

Answer:
PE = 882 J
Explanation:
Through the International System we know that the gravity of the earth is 9.8 m/s², so...
Data:
- m = 45 kg
- g = 9.8 m/s²
- h = 2 m
- PE = ?
Formula:
Replace and solve:
The potential energy of the sled is <u>882 Joules</u>.

Answer:
the answer is 0 .75m
Explanation:
where are finding the distance the speed is given as well as the time..so you multiple the speed with the time thus you get the distance..i hope that's the answer..
