Step-by-step explanation:
Number for Breaststroke = 50
Number for Butterfly = 25
Ratio of Breaststroke to Butterfly
= 50 : 25 = 2 : 1.
The ratio value is 2/1.
The choice A will be the correct choice dealing with proportion
Answer:
Step-by-step explanation:
Both cars, X and Y travelled 80 miles each.
Speed = distance/time
If car X took 2 hours to travel 80 miles, it means that the speed at which car X travelled is
80/2 = 40 mph
If car Y traveled at an average speed that was 50 percent faster than the average speed of car X, it means that the speed at which car X travelled is
40 + 0.5 × 40 = 60 mph
Time = distance/speed
Therefore, time taken by car Y to travel 80 miles is
80/60 = 1.33 hours
The gcf of 36 and 48 is 12
