The speed of the train in miles per hour which is the ratio of the total distance covered and the total time taken to cover the distance is 9.79 mph
- Total distance covered = 7 and 5/6 miles = 7.83333 miles
- Total time taken = 4/5 of an hour = 0.8 hour
Recall :
Speed in miles per hour = Distance covered / time taken
- The speed of the train = 7.833333 ÷ 0.8 = 9.7916
- The speed of the train in miles per hour = 9.79 mph
Therefore, the speed of the train in miles per hour as calculated from the distance covered by the train over a certain period of time is 9.79 mph

Answer:
D.1/5, 2/10, 3/15
D.4/13
B.35.33 km/h
Step-by-step explanation:
Write three ratios equal to 7/35.
7/35
divide by 7 on top and bottom
1/5
1/5 * 2/2 = 2/10
1/5 * 3/3 = 3/15
Jeanne/Jake = 12/39
divide top and bottom by 3
4/13
212 km/6 hr
35.3333333 km/hr
to the nearest hundredth
35.33 km/hr
It would decrease because you are multiplying by a decimal.
