Answer:
5 mph
Step-by-step explanation:
The relation between speed, distance, and time is ...
speed = distance/time
Filling in the given values, we find the speed to be ...
speed = (1/4 mi)/(1/20 h) = (1/4)(20/1) mi/h = 5 mi/h
Elena's speed is 5 miles per hour.
Answer:
45
Step-by-step explanation:
1/3 of 90
= 1/3 * 90
= 90/3
= 30
Let the missing number be x.
2/3 of x
= 2/3 * x
= 2x/3
30 = 2x/3
Cross multiply,
2x = 30 * 3
2x = 90
x = 90/2
x = 45
Hence,
the missing number is 45.
So, what you need do in this question is find two fifths of 30 6 goes into 30 5 times so 2 fives is 10 so the answer is 10
tell me if you have any questions.
