Answer:
The distance to his office is 2.5 miles.
Step-by-step explanation:
Given : Wade bicycles at a speed of 10 miles an hour and arrives at his office in only 15 minutes.
To find : What is the distance in miles to his office?
Solution :
The relationship between distance, speed and time is
The speed of bicycle is 10 miles per hour.
Time taken is 15 minutes.
Converting into hours,
1 hour = 60 minutes
1 minute = 
hours
15 minute = 
hours
15 minute = 0.25 hours
Substitute the value sin the formula,
Therefore, The distance to his office is 2.5 miles.

If you're talking about dice than there are six sides of a die, right? 5 of those 6 numbers are divisors of 12. 1,2,3,4, and 6. 5/6 is 0.833... which is 83% of 6. So the probability of rolling divisors of 12 is 83%.
Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h
Step-by-step explanation:
Lets assume Malcolm maximum speed to be M km/h and Ravi maximum speed to be R km/h
Average of their maximum speed is; (M+R)/2 =260 km/h
This can be simplified to M+R= 260*2
M+R = 520.......................................(I)
When Malcolm's speed is doubled,
2M=R+80 km/h ----------------------(ii)
The two equations are;
M+R = 520 ------ M=520-R ----(i)
2M=R+80 ---------------------------(ii)
Replacing M with (i) above
2M=R+80
2(520-R) =R+80
1040 -2R =R+80
1040-80 = R+2R
960 = 3R
960/3 =R
320 =R
M+R =520
M=520-320 =200
Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h
