A car can travel 400 miles on a full tank of petrol. A more efficient car can travel 30% further. How many miles further can it
xxTIMURxx [149]

Answer:160 miles

Explanation:

You can work out this type of question by using the 'unitary' method, which means finding out how much for ONE.

If you set out the steps with short sentences it will be clearer.

On 15 gallons, a car can travel 400 miles÷15↓

On 1 gallon, a car can travel 400÷15=262

miles

Once you know the distance travelled on 1 gallon of fuel, you can work out the distance travelled for any number of gallons.

On 6 gallons the car can travel

6

×

26

2

3

miles.

(6 times further than on 1 gallon)

6

×

80

3

=

160

miles

A school has a parking lot that is 150.23 feet by 135.12 feet. What is the perimeter of the parking lot?
elena-14-01-66 [18.8K]

Answer: 570.70 ft

Step-by-step explanation:

The perimeter is the distance around the entire parking lot.

The measurement of 150.23 ft by 135.12 ft is half of the distance of the lot because it represents just two sides yet there are 4 sides.

The other two sides have the same measurement as this is a rectangle.

The perimeter of the parking lot is:

= (150.23 * 2) + (135.12 * 2)

= 570.70 ft
