A bus covers its journey at the speed of 80km/hr in 10hours. If the same distance is to be covered in 4 hours, by how much the speed of bus will have to increase ?

Answer 1

$\bf\huge\color{red}{SOLUTION;}$

Initial speed = 80km/hr
Total distance = 80 x 10 = 800km
New speed = 800/4 =200km/hr
Increase in speed = 200 - 80 = 120km/hr

Given,

A bus covers its journey at the speed of 80km/hr in 10hours.

Now,

Initial speed = $80km/hr$

Total distance = $80 × 10 = 800km$

New speed = $\frac{800}{4} = 200km/hr$

So,

Increase in speed

= $200 - 80$

= $120km/hr$

Therefore,

Final answer) 120 km/hr
