Hyperloop: Speed

The Hyperloop is a hypothetical new fast transport system between cities, which works by launching pods that carry people through a very low air pressure tunnel. The initial primary proposed route is from San Francisco to Los Angeles, a distance of 560 km 560~\mbox{km} . The Hyperloop is hypothesized to cover this distance in half an hour. If it does this at a constant speed, how fast is the speed of the Hyperloop in m/s ?


The answer is 311.11.

s = 560 km (560000 m)

t = 0.5 h (1800s)

v = s/t

v = 560000 m / 1800s

v = 311.111 m/s

Converting units, we have a distance of 560 km 1000 m 1 km = 560000 m 560 \; \text{km} \cdot \dfrac{1000 \; \text{m}}{1 \; \text{km}} = 560000 \; \text{m} and a time of 0.5 hr 60 min 1 hr 60 sec 1 min = 1800 sec . 0.5 \; \text{hr} \cdot \dfrac{60 \; \text{min}}{1 \;\text{hr}} \cdot \dfrac{60 \;\text{sec}}{1\; \text{min}} = 1800 \; \text{sec}. Therefore, the speed of the Hyperloop is 560000 1800 311.11 m/s . \dfrac{560000}{1800} \approx \boxed{311.11}\; \text{m/s}.

A lógica é simples. Comece transformando as unidades de comprimento e de tempo para metro e segundos respectivamente, em seguida aplique a fórmula para velocidade média. 560 KM = 560 * 1000 m = 560.000m 30 mim = 30 * 60 s = 1800s Velocidade média = 560000 / 1800 = 311.11 m/s

v = s t v=\frac{s}{t}

v = 560000 1800 v=\frac{560000}{1800}

v = 311.111 v=\boxed{311.111}

The speed of the Hyperloop is 560 k m / h × 2 = 1120 k m / h 560 km/h \times 2 = 1120 km/h .So the speed in m / s m/s is 1120 × 1000 m 3600 s \frac{1120 \times 1000m}{3600 s} = 11200 m 36 s \frac{11200m}{36 s} = 311 1 9 m / s 311 \frac{1}{9} m/s

using speed formula s=d/t=560000/1800=311.11m/s

speed=distance/time; speed=560 1000/30 60; 311.11m/s

{560 x 1000 [m]} : {30 x 60 [s]} = 560000/1800 = 311.110 [m/s] . Answer : 3.1111E+2

Let d d be the distance traveled. Let t t be the time to travel the distance, d d . Let v v be the speed. Since v v is a constant, we have d = v t v = d t . d = vt \implies v = \dfrac {d}{t}. For d = 560 km d = \text {560 km} and t = 0.5 hr = 1800 s t = \text {0.5 hr} = 1800 \, \text{s} , we have v = 311.11 m/s . v = \boxed {311.11 \, \text{m/s}}.

560 KM is 560,000 in meters. You divide that by 30 to get the speed in minutes and divide that by 60 to get it in 60 which makes it the answer 311.11 repeating

Speed = Distance/Time. Therefore Speed = 560/(1/2)= 1120 km/hr. To convert km/hr into m/sec 1120*5/18=311.11

the Hyperloop will cover distance 560 km i.e, 560000 m in time 30 min i.e, 1800 sec. Speed = distance/time u = 560000/1800 u = 311.11 m/s

560 km=560000 m half an hour=30 minutes=1800 seconds s=d/t =560000/1800 =311.11
