Answer:
55 ohms
Explanation:
if it was series circuit, then you just need to add all the resistances
Answer:
48 kmph
Explanation:
The question is asking you the kmph and that means the amount of kilometers travelled divided by the amount of hours. And if you want to think of it in a formula, SPEED = DISTANCE ÷ TIME
In this case, the amount of hours is 2.5 and the speed is 120km so 120/2.5 is 48
so the answer is 48 kmph
Answer:
Explanation:
18 km / h
= 300 m / min
12 km / h = 200 m / min
distance travelled in 200 minutes = 300 x 200 = 60000 m
distance travelled in 50 minute in return journey = 200 x 50 = 10000 m
total distance travelled = 70000 m
total time = 250 minute
speed = 70000 / 250
= 280 m / min
= 16.8 km / h
Total displacement = 60000 - 10000 = 50000 m
total time = 250 min
velocity = 50000 / 250
= 200 m / min
= 12 km / h
Answer:
600 km
6 hours
Explanation:
El tiempo que viaja el automóvil de 6 a 10 de la mañana es
La velocidad del coche es 150 km/hr
La distancia está dada por
A distancia recorrida a las 10 de la mañana es de 600 km.
Ahora el tiempo que se toma está dado por
El tiempo que se tarda en recorrer 900 km es de 6 horas.
