Answer:
20 meters
Step-by-step explanation:
Firstly we need to know that distance = speed * time
In this particular question, we have the time and the speed, we are only told to find the distance.
Now as we can see, the units are not consistent. While the average speed is 30mph, the time is not in hours but minutes. So practically, we have to convert the time to hours.
Since there are 60 minutes in an hour, the number of hours in 40 minutes would be 40/60 = 2/3 hours.
Now we can proceed to find the distance. We simply multiply the average speed with the time.
Hence, that is 30 * 2/3 = 20 meters
Answer:
4!
Step-by-step explanation:
Given four numbers 2, 4, 6, 8.
The numbers can be arranged to form an odd number which is less than 300.
That means we have three spaces to fill this. We can try out the different combination of the numbers.
Note that the numbers should be odd. So, in the unit digit should only be 5. 2, 4, 8 would make the number even.
Also, the first digit can only be two because other numbers would make it bigger than 300.
So, 2 ___ 5 is fixed. The middle digit could be any of the four.
So, 225; 245; 255 and 285 all satisfy the conditions.
So, four numbers can be formed.
Answer:

Step-by-step explanation:
Let the total amount be x
Then Ali got 1/8x With 7/8x left
Juma got 7/40x with 7/10x left
Musa, Khalid and Mustafa got 7/30x each
since 
7x=18000
