A bus travels 54 km in 90 minutes. Find the speed of the bus in m/s & k/m.

Academic Physics NCERT Class 7

Distance traveled by the bus $=54\ km=54\times1000\ m=54000\ m$

Time taken to travel $=90\ minute=90\times60\ s=5400\ s$

Therefore, the speed of the bus $=\frac{54000\ m}{5400\ s}=10\ m/s$

And the speed of the bus in $km/m=\frac{54\ km}{90\ m}=0.6\ km/m$

The distance between two bus stops is 5 km. A bus travels the distance in 20 min. What is the speed of the bus? Also, convert it into $\frac{m}{s}$ . Can it also be called as the average speed of the bus?
A bus accelerates uniformly from 54 km/h to 72 km/h in 10 seconds Calculate the acceleration in $m/s^2$.
Convert a speed of 54 km/h into m/s.
Bus X travels a distance of 360 km in 5 hours whereas bus Y travels a distance of 476 km in 7 hours. Which bus travels faster ?
Roohi travels 300 km to her home partly by train and partly by bus. She takes 4 hours if she travels 60 km by train and the remaining by bus. If she travels 100 km by train and the remaining by bus, she takes 10 minutes longer. Find the speed of the train and the bus separately.
The distance between two bus stops is 5 km, a bus travels the distance in 20 min. What is the speed of the bus? Also, convert it in meters per second. Can it also be called as the average speed of the bus?
A bus increases its speed from $36\ km/h$ to $72\ km/h$ in $10\ seconds$. Its acceleration is:(a) $5\ m/s^2$(b) $2\ m/s^2$(c) $3.6\ m/s^2$(d) $1\ m/s^2$
Ankita travels \( 14 \mathrm{~km} \) to her home partly by rickshaw and partly by bus. She takes half an hour if she travels \( 2 \mathrm{~km} \) by rickshaw, and the remaining distance by bus. On the other hand, if she travels \( 4 \mathrm{~km} \) by rickshaw and the remaining distance by bus, she takes 9 minutes longer. Find the speed of the rickshaw and of the bus.
If a bus travel 48 kilometre in 40 minutes, what will be speed of bus ?
A man is \( 45 \mathrm{~m} \) behind the bus when the bus start accelerating from rest with acceleration 2.5 \( m / s^{2} \). With what minimum velocity should the man start running to catch the bus.(a) \( 12 \mathrm{~m} / \mathrm{s} \)(b) \( 14 \mathrm{~m} / \mathrm{s} \)(c) \( 15 \mathrm{~m} / \mathrm{s} \)(d) \( 16 \mathrm{~m} / \mathrm{s} \)
Namita travels 20 km 50 m every day. Out of this she travels 10 km 200 m by bus and the rest by auto. How much distance does she travel by auto?
A bus travels a distance of 120 km with a speed of 40 km/h and returns with a speed of 30 km/h. Calculate the average speed for the entire journey.
Jason's office is \( 15 \frac{2}{5} k m \) from his home. He walks $1 \frac{1}{2} k m $ from home and travels a distance of $ 5 \frac{1}{2} k m $ in an auto to reach the bus-stand. He covers the remaining distance to his office by bus. What distance doesJason travel by bus?Express the answer as a mixed fraction.
