At 3: 00 a car passes mile marker 74 as it cruises along the highway. the car then passes mile marker 124 as the
clock reads 3: 45. how fast was the car moving?

Speed = (distance covered) / (time to cover the distance)

Distance covered = (end distance) minus (start distance)

Distance covered = (124 - 74) = 50 miles

Time to cover the distance = (3:45 - 3:00) = 45 minutes or 0.75 hour

Speed = (50 miles) / (0.75 hour)

Speed = 66 and 2/3 mph
