Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Answer: your answer is B
Explanation: Seismic waves causes potential energy that accumulates in a fault to transfer to the surface during an earthquake.
Work:
1 kilometer = 1000 meters
45 × 60 = 2700
W = F × D
W = 2,000 N × 1,000 m
W = 2,000,000 J
P = W ÷ t
P = 2,000,000 J ÷ 2,700 s
P = 741 watts
Answer:
741 watts of horse power.
