A
Step-by-step explanation:
Answer: 11.73 seconds
Step-by-step explanation:
To solve the question, we have to add the time used by Giselle, Sarah and Aliyah and then subtract from 41.37 seconds to determine the time used by Kelly. This will be:
= 41.37 - (9.36 + 9.71 + 10.57)
= 41.37 - 29.64
= 11.73 seconds
Kelly used 11.73 seconds
Answer:
132°
Step-by-step explanation:
Angle JKH and IHK are alternate interior angles, and thus congruent.
Since JKH is 132 degrees, so is IHK
We are given with
walking speed = 5 km/hr
bus speed = 60 km/hr
total distance = 35 km
total time = 5 hr
To solve this, we use the equations
x + y = 5
5x + 60y = 35
The solution is
x = 4.82 hr
y = 0.18 hr<span />
