Answer:
The speed of Kali is 30 mph.
Step-by-step explanation:
Let, the speed of Kali be "x", then speed of Ndiba will be:
Speed of Ndiba = x + 15 mph
If, the time for travel for Ndiba is 2 hrs, when he catches Kali, and he left 1 hour later than Kali, then then time traveled by Kali at that instant will be 2+1 = 3hrs.
At the point of meeting both will have covered same distance.
Distance Covered by Kali = Distance Covered by Ndiba
(Speed of Kali)(Time traveled by Kali) = (Speed of Ndiba)(Time traveled by Ndiba)
(x)(3) = (x +15)(2)
3x = 2x +30
<u>x = 30 mph</u>
The correct answer is, actually 30 mph, by the solution shown above.
Answer:
x=31°, y=52°,z=97°
Step-by-step explanation:
The interior angles of a triangle sum up to 180°
y°+ 31°+ 97°= 180°
y° = 180 - 31° - 97°
y=180°-128°
y° = 52°
Alternative angles are equal
x= 31°
Two opposite angles of a parallelogram are equal
z°= 97°
Therefore x=31°,y=52° and z=97°
The last choice is correct.
