1 hr = 60 min
1 min = 60 sec
time = distance/speed
= 67 km ÷ 100 km/h
= 0.67 hours
= 0.67 × 60 min
= 40.2 min
0.2 min = 0.2 * 60 sec = 12 sec
→ It will take 40 minutes 12 seconds

3 hours and 10 minutes!
Well, isn't that a lovely question! Sound travels at about 343 meters per second in air. To find out how long it will take for sound to travel 40,000 kilometers, we need to convert that distance to meters and then divide it by the speed of sound. So, it will take approximately 32 hours for the sound to travel that distance. Just imagine all the beautiful landscapes and happy little trees the sound will pass along the way!
Dividing distance travelled by speed gives 100/80 = 1.25 hours or 1 hour 15 minutes.
It would take 40 minutes !
