Answer:
3 hours
Step-by-step explanation:
250 = 50h + 100(4 - h)
250 = 50h + 400 - 100h
250 = -50h + 400
-150 = -50h
h = 3
At that rate, cyclists will cover a distance of 57 meters in 3 seconds.
The ratio of two related quantities expressed in several units is known as a rate.
Speed is the ratio of the distance traveled in a period of time. Speed is given by:
Speed = distance/time
The cyclist's speed, given that he completes 380 meters in 20 seconds, will be:
Speed = distance/time
s = d/t
v = 380 m / 20 s
v = 19 m/s
If he travels at this rate, at 3 seconds, the distance is:
Speed = distance/time
Distance = Speed × time
d = s × t
d = 19 m/s × 3 s
d = 57 m
Therefore,
At that rate, the cyclist will travel a total distance of 57 meters in 3 seconds.

Answer:
x = 5.
Step-by-step explanation:
The break even point is when they are equal:
76x = 36x + 200
40x = 200
x = 200/40
x = 5.
