a car has ti travel 280 km in 5 hrs but it already travelled 150 km ( it is moving with soeed of 50 km per hour for 3 hours )
remaining time = 2 hours
remaining distance = 280 - 150 = 130 km
by using formula Speed = distance / time
S = 130 / 2
S = 65 km per hour
remaining time = 2 hours
remaining distance = 280 - 150 = 130 km
by using formula Speed = distance / time
S = 130 / 2
S = 65 km per hour
