Answer:
40 min is the answer
Step-by-step explanation:
To solve this we need to convert all the units into SI units
for ritu,
speed= 90km/hr
= 90 × 1km/ 1hour
= 90×1000/3600 m/s
= 25m/s
distance = 120×1000m
time = distance/ speed
= 120000/25
= 4800sec
= 4800/60min
= 80 min
for garima,
distance =120×1000m
speed = 60km/hr
= 60×1000/3600 m/s
=100/6 m/
time = 120000/(100÷6)
= 7200sec
= 7200÷60 min
= 120 min
time difference is 120-80 = 40 min
Answer:
<em>(D). (8, - 5) </em>
Step-by-step explanation:
Coordinates of a center of a circle (x - h)² + (y - k)² = r² is (h, k)
Coordinates of the midpoint are ( 
, 
)
(x² - 10x + 25) + (y² + 2y + 1) = 25
(x - 5)² + (y + 1)² = 5²
(5, - 1) are coordinates of the center of the circle and (5, - 1) is a midpoint of the segment connected (2, 3) and (x, y)
5 = (2 + x) / 2 ⇒ x = 8
- 1 = (3 + y) / 2 ⇒ y = - 5
<em>(D). (8, - 5)</em>
The absolute value of -18 is 18
Answer:
y=-x+4
Step-by-step explanation:
I believe it’s 220 because if u do 24 hours that’s 160 which then u can count up to 32 which is 240 which u can take two away
