The total distance D travelled by John is given by

The total distance D travelled by John is given byD = 45×2+55×3

The total distance D travelled by John is given byD = 45×2+55×3D = 90+165

The total distance D travelled by John is given byD = 45×2+55×3D = 90+165D = 255 miles.

Answer 2

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.
