serg [7]

Complete question is;

Roger and Rita each drive at a constant speed between Phoenix and San Diego. Each driver’s distance for the same section of the trip is displayed below. Who had a head start, and how many miles was the head start?

A) Rita had a 28-mile head start.

B) Roger had a 26-mile head start.

C) Roger had a 25-mile head start.

D) Rita had a 22-mile head start.

Answer:

A) Rita had a 28-mile head start.

Step-by-step explanation:

Let's assume that Roger travelled a distance of 60 miles

And that;

Rita travelled a distance of 32 miles

We are told that they travelled between Phoenix and San Diego.

Thus, it means that if they have different distances but covered same section of the trip, it means the one with higher distance started before the section of the trip.

Thus, it means that Rita had a head start of Roger since she covered only 32 miles.

Thus;

Rita had a head start of; 60 - 32 = 28 miles

An airplane is flying from knoxville to new york. The distance it travels in miles, d, is related to the time in seconds, t, by

Zigmanuir [339]

Answer:

0.12 miles is it flying per second.

Step-by-step explanation:

The distance d is related to time t in seconds is given by the equation as follows :

d =0.12 t

We need to find how many miles is it flying per second.

$\dfrac{d}{t}=0.12\\\\\dfrac{\text{miles}}{\text{second}}=0.12$

So, the speed of the airplane is 0.12 miles per second, Hence, 0.12 miles is it flying per second.

Need help rn please?/..Thank you. Multiple step equation

liubo4ka [24]

Answer:

The answer (using BEDMAS) is 27

Step-by-step explanation:

The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS

First solve the smaller bracket

18 + 2 = 20

So then it becomes 9 x [20 ÷ 5 - 1]

Do the division inside the bracket next

20 ÷ 5 = 4

Then it becomes 9 x [4 - 1]

Do then subtraction within the bracket

4 - 1 = 3

Then it becomes 9 x 3

Finally solve 9 x 3 which equals 27
