Answer: 37.5 km
Explanation:
The question is that
If you ran 15 km/hr for 2.5 hours, how much distance would you cover ?
Where
Speed = 15 km/ hr
Time = 2.5 hours
Using the formula for speed.
Speed = distance/time
Substitute speed and time into the formula
15 = distance/ 2.5
Make distance the subject of formula by cross multiplying.
Distance = 15 × 2.5
Distance = 37.5 km.
Answer:
the first one looks like a spiral galixy
the 2nd one looks like a lenticular galixy ?? (im pretty sure but not 100%)
the 3rd one looks like a elliptical galixy
Explanation:
The period of the wave is the reciprocal of its frequency.
1 / (5 per second) = 0.2 second .
The wavelength is irrelevant to the period. But since you
gave it to us, we can also calculate the speed of the wave.
Wave speed = (frequency) x (wavelength)
= (5 per second) x (1cm) = 5 cm per second
There is something wrong, 56 supposed to be 5/6 and 7575 is only 75 passengers.
So to solve for this problem:If an airplane carries 75 passengers and if it is 5/6 of the capacity which is x, then we can say that:
5/6 * x = 75
5x/6 = 75
5x = 75 x 6
5x = 450
5x/5 = 450/5
x = 90
The capacity of the airplane is 90
The following is eawual if 87 is 2 times the size
