Question

To solve these problems.

1. What distance did a car travel that went 70 mph for 6 hours?
2. What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?

Answer 1

Solution(s):

1) What distance did a car travel that went 70 mph for 6 hours?

Given:

• 70 miles = 1 hour

Multiply the RHS by 6 to see what distance was covered by the car in 6 hours.

• 70 miles = 1 hour
• => 70 x 6 miles = 6 hours
• => 420 miles = 6 hours

The car traveled 420 miles in 6 hours.

2) What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?

Given:

• Length: 7 cm
• Breadth: 4 cm

Formula to find perimeter: 2(L) + 2(B)

Substitute the values into the formula to find the perimeter.

• 2(L) + 2(B)
• => 2(7) + 2(4)
• => 14 + 8
• => 22 cm

The perimeter of the rectangle is 22 cm.
