Question :
A bus travels 108 km in 45 minutes. Find the speed of the train in terms of m/s as well as km/hr.
To Find :
Speed of Train in terms of m/s and km/hr
Given :
Distance that can be travelled in 45 minutes = 108 km
Answer :
45 minutes = 3/4 Hour
In terms of km/hr :
108 km/3/4 hour
(108 × 4)km/3 hour
= 432 km/3 hour
= 144 km/hour
In terms of km/hr : 144 kmph
To find value in m/s , just multiply the vlue in kmph with 5/18
144 × 5/18 m/s
= 720/18 m/s
= 40 m/s
In terms of m/s : 40 m/s
