The distance between two cities is 145 miles. A truck can cover this distance in 2. 5 hours. A car is 1. 5 times as fast as the

Sophie [7]

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 1 hour

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:

$\displaystyle Speed = \mathbf{ \frac{Distance}{Time}}$

$\displaystyle Speed \ of \ the \ truck, \ v_{truck} = \frac{145 \ miles}{2.5 \ hours} = \mathbf{58 \ mph}$

Therefore;

The speed of the car, $v_{car}$ = 1.5 × 58 mph = 87 mph

At the time, t, the truck and the car meet, we have;

$\mathbf{v_{car} \times t + v_{truck} \times t = d}$

Which gives;

87 × t + 58 × t = 145

$\displaystyle t = \mathbf{\frac{145}{87 + 58}} = 1$

The time it takes them to meet, t = 1 hour

Terry made 6 orders in September, 36 orders in October, and 216 orders in November. If this pattern continues, how many orders w

bixtya [17]

Answer:

1296 orders

Step-by-step explanation:

There is a pattern to his orders.

First, he starts with 6.

Second, he made 36.

Third, he made 216.

From here, the pattern can be identified. And, you can extend it further.

Pattern - x · 6

x = the orders.

6, 36, 216

6 (September) × 6 = 36 (October)

36 × 6 = 216 (November)

216 × 6 = 1296 (December)
