Question

2. A bus travelling at 42 km/h covers a distance in 5 h. How much time would it save if it
increased its speed by 8 km/h?
​

Answer 1

Answer:

4.2hr

Step-by-step explanation:

we know that distance=speed× time

=42×5

If the speed is increased by 8km/hr then the new speed is 42+8=50km/hr

Now the time taken = distance/speed

=210/50

=21/5

=4.2hr
