I’m not too sure but I think it’s 8,91 m/s2
Answer:
58.24 Km/h.
Explanation:
From the question given above, the following data were obtained:
Distance (d) = 495 Km
Time (t) = 8 h 30 mins
Speed (S) =?
Next, we shall express 8 hours 30 mins to hours.
We'll begin by convert 30 mins to hour.
60 mins = 1 h
Therefore,
30 mins = 30 mins × 1 h/ 60 mins
30 mins = 0.5 hour.
Thus,
8 h 30 min = 8 + 0.5 = 8.5 hours
Speed is define as the distance travelled per unit time. Mathematically, it is expressed as:
Speed = Distance /time
With the above formula, we can obtain the speed as shown below:
Distance (d) = 495 Km
Time (t) = 8.5 hour
Speed (S) =?
Speed = Distance /time
Speed = 495 Km / 8.5 hour
Speed = 58.24 Km/h
Thus, the speed is 58.24 Km/h.
Answer:
The average speed of the cars is 50mph
Explanation:
Option C
Both are temples designed to inspire reflection, meditative thought and are places of significant art and design. The Ryoanji garden uses asymmetry, spacial composition, minimalism and little color that arranges three small islands in a perfectly kept graveled garden with a prominent cherry blossom; the stained glass window at Chartres Cathedral, however, uses light, complicated symmetrical patterns, figuration, lots of color on the two-dimensional form of the glass.
