50 ft because you times 20 by 40 then you divide by 100 because that is the total percent
75% of the repair bill is 53.25
0.75x = 53.25
x = 53.25 / 0.75
x = 71 <== total cost of the bill

Step-by-step explanation:
Answer:
20 miles per hour
Step-by-step explanation:
Given that the train left for London, and after 9 hours later, a car traveling 80 miles per hour tried catching up to the train. After 3 hours, the car caught up
Which means that the car travelled the same distance in 3 hours as the train travelled in 9 + 3 = 12 hours
Let the distance be d
Given the speed of car is 80 miles per hour
We know that 

d = 240 miles
Now for the train Average speed = total distance / total time taken
Average speed of the train =
= 20 miles per hour
