Answer:
Width: 255 feet
Length: 180
Step-by-step explanation:
Hi there!
Perimeter = 2 × width + 2 × length
Let w be equal to the length of the base
Plug in the given information:
870 = 2 × w + 2 × (w-75)
870 = 2w+2w-150
870 = 4w-150
4w=1020
w=255
Therefore, the width of the base is 255 ft.
To find the length of the base, subtract 75 from 255:
255-75 = 180
I hope this helps!
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
