Step-by-step explanation:
It would be 29 and a little more but she would need 30 and have leftovers.
55/8 or 55:8 will be the unit rate I think
You just put two numbers that you can multiply to get the number and when you came divide anything else in the number then you circle it and that's one of the numbers
24 units because 12*4=48 and 48/2=24
Answer:
r = 6 mph and f = 11 mph
Step-by-step explanation:
Representations:
1) speed of faster cyclist: f = r + 5
2) speed of slower cyclist: r
Distances covered:
(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)
Then 5r + 25 + 5r = 55, or, after reducing this equation:
r + 5 + r = 11, or
2r = 6
Then r = 6 mph and f = 11 mph
