distance = d
speed 1 = 48 km/hr
Time 1 = t/60
Speed 2 = 60 km/hr
Time 2 = (t - 6)/60
distance = speed*time
48*t/60 = 60*(t-6)/60
4/5t = t-6
6=t-4/5t
6=t/5
t=30 mins
distance = speed 1 *time 1
distance = 48*30/60 = 24 km
distance = speed 2 * time 2
distance = 60 * (30-6)/60 = 24 km
Distance = 24 km
speed 1 = 48 km/hr
Time 1 = t/60
Speed 2 = 60 km/hr
Time 2 = (t - 6)/60
distance = speed*time
48*t/60 = 60*(t-6)/60
4/5t = t-6
6=t-4/5t
6=t/5
t=30 mins
distance = speed 1 *time 1
distance = 48*30/60 = 24 km
distance = speed 2 * time 2
distance = 60 * (30-6)/60 = 24 km
Distance = 24 km
Thanks!
