Answer:
x<2.5
Step-by-step explanation:
-4x +5>-5
-4x>-5-5
-4x>-10
x<10/4(on multiplying (-)ve sign both the sides inequality changes)
x < 2.5
Answer:
<u>The semi-trailer truck has the fastest average speed</u>
Step-by-step explanation:
Let's recall that the formula of the average speed is:
Average speed = Distance/Speed
Now, we can calculate the average speed for each class of vehicle, as follows:
Flatbed truck average speed = 144/5 = 28.8 miles per hour
<u>Semi-trailer truck average speed = 327/4 = 81.75 miles per hour</u>
Tanker truck average speed = 589/15 = 39.27 miles per hour
Which truck has the fastest average speed?
<u>The semi-trailer truck has the fastest average speed</u>
Answer:
<h2>
Average speed is 15km/h</h2>
Step-by-step explanation:
Step one:
given data:
total distance =7.5km
time taken= 30 min= 0.5 hours
we know that the average speed is the average distance divided by time taken
Step two:
mathematically expressed as
speed=distance/time
substituting we have
speed=7.5/0.5
speed=15km/hour
Hence the average speed is 15km/h
To find a median of an even amount of numbers, add the two middle numbers, and divide by two.
45 + 46 = 91
91/2 = 45.5
45.5 is your median
