Answer:
Marcela tardó 6 horas y Roberto tardó 8 horas.
Step-by-step explanation:
Dado que Marcela tardó dos horas menos que Roberto en recorrer una distancia en bicicleta, y sabiendo que el producto de los dos tiempos es de 48 horas, para determinar cuánto tardó cada uno se debe realizar el siguiente cálculo:
M = X
R = X + 2
X x (X + 2) = 48
8 x 6 = 48
Por lo tanto, Marcela tardó 6 horas y Roberto tardó 8 horas.
Explanation:
The average value of the velocity function is the height of the rectangle that has the same area as the velocity curve. That height is still measured in m/s.
If you want to find distance traveled (in m), then you must multiply the height in m/s by the width in s.
It assumes that a satellite takes 86.54 minutes to go around the earth
If the groups are all made up of 10 pennies and she added 5 groups, then
5 x 10 = 50
Which means she added 50 pennies to the jar and now has 150 pennies. :)
Answer:
10cm represents $10
2cm represents $2
10cm also represents 1week
For every week Andre checks 10cm, deduct 2cm which represents $2 donation for food bank, and remaining 8cm represents $8 left for his Dad's gift.
in 5weeks, which is 50cm, save $8 per week/ per 8cm = $8 × 5 = $40
in 5weeks, which is 50cm, he donate $2 per week/ per 2cm = $2 × 5= $10
