Speed = distance/ time
S = ?
D= 15 km
T = 15 min
convert time into hour
15 min = 15/60 hour = 0.25 hour
now,
S = 15/0.25
S = 60 km/hr

According to the question, a train covers 20 km distance in 15 minutes with a constant speed, so here we have to determine the speed of the train,
We all know that Distance= Speed ×Time
So, Speed= Distance/Time
here in this question
time = 15 minutes = 1/4 hour = 0.25 hour
Distance= 20 kilometers
Constant speed=?
So the speed= distance/time = 20/0.25 km/hr = 80 km/hr
So the constant speed would be 80 km/hr
