Answer:
32 remainder 2
Step-by-step explanation:
To divide 162 by 5, we simply do the following:
5 goes into 16 => 3
Multiply 5 by 3 => 3 × 5 = 15
Subtract 15 from 16 => 16 – 15 = 1
Put the 1 before 2 => 12
5 goes into 12 => 2
Multiply 5 by 2 => 5 × 2 = 10
Subtract 10 from 12 => 12 – 10 => 2
In summary,
162 divided by 5 => 32 remainder 2

The relative speed of the car to the truck while moving towards each other is the sum of the speed of both vehicles.
- The time it takes them to meet is <u>1 hour</u>
Reasons:
The distance between the cities, d = 145 miles
The time it takes a truck to cover the distance = 2.5 hours
The speed of the car = 1.5 × Th speed of the truck
Required:
The time it takes them to meet if they are moving towards each other.
Solution:
Therefore;
The speed of the car, = 1.5 × 58 mph = 87 mph
At the time<em>, t</em>, the truck and the car meet, we have;
Which gives;
87 × t + 58 × t = 145
- The time it takes them to meet, <em>t</em> = <u>1 hour</u>
