Answer:
5 mph.
Step-by-step explanation:
Let the runner travel at x miles an hour , then the cyclist travels at 5/ 3 * x
= 5/3 x miles an hour.
So we have the equation
5/3 x - x = 2 ( since the cyclist was travelling at 2 mph faster).,
2/3 x = 2
x = 3/2 * 2 = 3 mph.
So the cyclists speed was 3 * 5/3
= 5 mph.
Answer:
x < 6/7
Step-by-step explanation:
Multiply both sides by 3 to get 7x < 6
Divide by 7
x < 6/7
The unit fraction of 7/8 is 1/8
Answer:
