Jim went by bus to visit his uncle. He left at 10 A.M. and arrived at 4 P.M. The bus traveled 270 mi. What was its average speed
Feliz [49]

Answer:

Average speed, S = 45 mph

Step-by-step explanation:

<u>Given the following data;</u>

Take-off time = 10 AM

Arrival time = 4 PM

Distance = 270 miles

To find the average speed of the bus;

First of all, we would determine the total time.

10 AM to 4 PM = 6 hours

Total time = 6 hours

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

Speed = \frac{distance}{time}

Substituting into the formula, we have;

Speed = \frac{270}{6}

<em>Average speed, S = 45 mph</em>

<em />

<em>Therefore, the average speed of the bus is 45 miles per hour.</em>

Which inequality is a true statement?
max2010maxim [7]

Answer:

The true answer is " -3 < -1.

Step-by-step explanation:

I say this because these numbers are negatives. If you put them on a number line you can see that the bigger numbers are farther from the postitives. Postitive numbers are bigger so whatever is close to them is bigger. So because (-1) is closer to them it would be greater, which is what the symbol "<' states.
