Question

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:

time saved is 48 minutes

Answer 2

• Distance travelled= Speed x Time =42 x 5= 210- Kms.

• On increasing the speed by 8- Km/h, the speed=(42+8)= 50- Km/h.

• So time taken to travel at the new speed= 210/50= 4.2- hours.

• Time saved = 5- hours -(4.2- hours) =0.8- hours

• = 48 minutes. ★

Aɴsᴡᴇʀ:-

Time required when speed is increased by 8km/hr is 48 mins.
