Answer:
The train travels 40 m
Explanation:
* Lets explain how to solve the problem
- The distance = speed × time
- The train travels 80 mph for 30 minutes
∵ The train travels at speed 80 mph
∵ The train travels for 30 minutes
- We must change the minutes to hours
- There are 60 minutes in an hour
∵ 1 hour = 60 minutes
∴ 1 minute = 1/60 hour
∵ The train traveled for 30 minutes
∴ The train traveled for = 30 × 1/60 = 1/2 hour
∵ Distance = speed × time
∵ The speed = 80 mph
∵ The time = 1/2 h
∴ The distance = 80 × 1/2 = 40 m
* The train travels 40 m
