400 m in 8 hours
200 m in 4 hours
100 m in 2 hours
50 m in 1 hour
His average speed is 50mph
Answer:
1/2
Step-by-step explanation:
Anything with an exponent of 1 is itself.
2 1/5x * 1 7/10 y * 4 3/5 x 1 7/10 (* 7 4/50)
Finds the answer
10 6/50x * 7 41/50y (* 7/4/50) = 56
79 13/100 (* 7 4/50) = 56
560 = 56 (10x)
x = 5 6/10
7 (y) = 56 (7y)
8 = 56/7 (y)
y = 8
x = 5 6/10
6/10 of 560 = 336
336/60 = x
336/60 = 5 6/10
