Step-by-step explanation:
102 divided by 2 is 51
Answer:
the length = 18 feet and width = 9 feet
Step-by-step explanation:
Step 1:
Assume
Length of the rectangle = b
Width of the rectangle = a
Step 2:
As mentioned in the question length is double the width therefore;
b = 2*a
Step 3:
as mentioned in the question James need total 54 feet to cover the pool that means the perimeter of the pool is 54 feet therefore perimeter formula can be used as follows;
P = 2a + 2b
54 = 2a +2(2a) <equation from step 2 has been used for b>
54 = 2a + 4a
54 = 6a
a = 54/6
<u>a = 9 feet</u>
Step 4:
Now again use equation from step b to find out the length;
b =2a
take value of a from step 3
b = 2*9
<u>b = 18 feet</u>

Answer:
Given,
Distance traveled = 20 km
Speed = 60 km/h
So, timetaken=DistanceSpeed=2060=13h
For the next journey
Distance traveled = 20 km
Speed = 80 km/h
So, timetaken=DistanceSpeed=2080=14h
Now,
Total distance traveled = 20 + 20 = 40 km
Total time taken = 13+14=712
We know,
Averagespeed=TotaldistancetraveledTotaltimetaken=40712=68.5 km/h
Hence the average speed of the train is 68.5 km/h
2limes=0.36
we simplify /2
1lime=0.18
times by 3
3limes=0.54
