Answer:
150 miles
Explanation:
The relationship between speed, time and distance is such that the product of speed and time is distance.
Given that they drove the same speed throughout the trip
Speed on day one given that distance covered is 300 miles in 6 hours,
Speed = 300 miles/ 6 hours
= 50 miles per hour
Speed on day two given that distance covered is 250 miles in 5 hours
= 250 miles/ 5 hours
= 50 miles per hour
If on the third day, the speed is maintained and they drove for 3 hours,
Distance covered = 50 miles per hour × 3 hours = 150 miles
