Answer:
The speed is 2/9 miles per minute
Step-by-step explanation:
Speed is defined as the distance covered per unit time.
The formula for speed is given by:

Let s be the speed, d be the distance and t be the time then

Given

The speed will be calculated by dividing the number of miles by minutes
So putting the values in the formula

Hence,
The speed is 2/9 miles per minute
3/4
3.0/4=0.7R0.2 or 0.7 + 0.2/4
0.20/4=0.05R0.00 or 0.05 + 0.00/4
now put it all together
0.7R2 = 0.7 + 0.05R0.00 = 0.75 + 0.00 = 0.75
The answer is 0.1
17/10 - 8/5 = 0.1
