A vehicle travels 180 miles in 4 hours. At this rate, how many miles will the vehicle travel in 6 hours?

Answers

Answer:

270 miles

Step-by-step explanation:

Divide 180/4 = 45

180 + 90 = 270

A vehicle can travel 180 miles in 4 hours, then in 6 hours, the vehicle will travel 270 miles.

What is an arithmetic operation?

The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the data given in the question,

Distance travelled by the vehicle = 180 miles

Time is taken to travel 180 miles = 4 hours

Distance travelled in 1 hour = 180/4 = 45 miles

Then,

Distance travelled in 6 hours = 6 × 45 = 270 miles.

Answers

Given:

[tex]\overline{AE}\cong \overline{DE}, \overline{AB}\cong \overline{DC}[/tex]

To prove:

[tex]\Delta ABE\cong \Delta DCE[/tex]

Solution:

In triangle AED,

[tex]\overline{AE}\cong \overline{DE}[/tex]

Two sides of triangle AED are equal, it means triangle AED is an isosceles triangle. The base angles of an isosceles triangle are equal. So,

[tex]\angle A\cong \angle D[/tex]

In triangle ABE and triangle DCE,

[tex]\overline{AE}\cong \overline{DE}[/tex] (Given)

[tex]\angle A\cong \angle D[/tex] (Base angles of an isosceles triangle are equal)

[tex]\overline{AB}\cong \overline{DC}[/tex] (Given)

Two corresponding sides and their included angles are congruent. So, triangles are congruent by SAS postulate of congruence.

[tex]\Delta ABE\cong \Delta DCE[/tex] (By SAS postulate of congruence)

Hence proved.
