a car and a bus are travelling toward each other . they are 510 km apart at 13 20 and they pass each other at 16 20 . if the car is travelling at the speed of 90 km/h find the speed of the bus
Answers
At 13:20, they are 510 km away from each other.
At 16:20, the distance has been covered.
Total time taken=16:20-13:20=3:00 hours
Speed of car=90km/hr
In three hours the car will cover a distance=speed*time
=90km/hr*3hr
270km
So the distance left will be covered by the bus i.e. it will cover a distance=240km
Speed of the bus=Total distance travelled /Total time taken
=240 km/3 hr=80 km/hr
The speed of the bus will be 80 km/hr
Answer:
Step-by-step explanation:
Let the speed of bus be x
Since they are travelling in opposite direction :
relative speed = 90+x = 510/3
⇒ 90+x = 170
⇒ x = 170-90 = 80
