Answer:
B) 24
Step-by-step explanation:
distance = 6 km
we want the speed in km/h, so let's turn everything into either km or h if possible
time = 7:45 am - 7: 30 am = 15 minutes
60 minutes = 1 hour
1 hour / 60 minutes = 1
15 minutes * 1 = 15 minutes * 1 hour/60 minutes = 15 / 60 hours = 1/4 hours = 0.25 hours
note that we multiply by 1 hour / 60 minutes, not 60 minutes/ 1 hour. this is because we want the minutes to cross out -- because the original is given in minutes ( 15 minutes = 15 minutes/1) and is in the numerator, we need minutes in the denominator of 1 hour/60 minutes to cross it out
km = 6
h = 0.25
km/h = 6/0.25 = 24
D)42 because u first have to multipy left to right then divide left to right then do the same thing with add and subtract
Answer:
In the first case x and y be 49 and 47 respectively
In the second case x and y be 41 and 37 respectively
Step-by-step explanation:
Let us assume the two number be x and y
In the first case
Now
x + y = 96
x - y = 2
2x = 98
x = 49
y = 49 - 2 = 47
So x and y be 49 and 47 respectively
In the second case
x + y = 78
x - y = 4
2x = 82
x = 41
y = 78 - 41 = 37
So x and y be 41 and 37 respectively
