Match each travel scenario to the correct amount of time it takes to complete the journey.
- A delivery van drives miles at an average rate of mph. hours
- A cargo ship sails miles at a constant rate of mph. hours
- A marathon runner covers miles at a steady pace of mph. hours
- A commuter train travels miles at an average rate of mph. hours
Cevap
The delivery van takes 3 hours, the cargo ship takes 4 hours, the marathon runner takes 2 hours, and the commuter train takes 5 hours.
Each correct match is determined by taking the stated distance in miles and dividing it by the average speed in miles per hour (). Because the difficulty is intentionally basic, all divisions result in clean, whole-number integer hours.
