Answer:
- John drove 255 miles.
Explanation:
Given that:
- John left home and drove at the rate of 45 mph for 2 hours.
- He stopped for lunch then drove for another 3 hours at the rate of 55 mph to reach his destination.
To Find:
- How many miles did John drive?
We know that:
- Distance = Speed × Time
Finding the distance covered by John before lunch:
We have,
- Speed = 45 miles/hour
- Time = 2 hours
- Distance = (45 × 2) miles
- Distance = 90 miles
Finding the distance covered by John after lunch:
We have,
- Speed = 55 miles/hour
- Time = 3 hours
- Distance = (55 × 3) miles
- Distance = 165 miles
Finding the total distance covered by John:
Total distance = Distance covered before lunch + Distance covered after lunch
- Total distance = 90 miles + 165 miles
- Total distance = 255 miles
∴ Total distance covered by John = 255 miles
Answer: John drove 255 miles.
