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:
72 units
Step-by-step explanation:
A circle has a circumference of 452.16
The formula for circumference of circle = 
Where r is the radius of circle
The approximate value of pi = 3.14
Given circumference C= 452.16



Divide both sides by 6.28
r = 72
So radius of the circle 72 units
Answer:
y-3=0 (x+6)
Step-by-step explanation:
Hope im right :)
First convert 8 mm to cm.
We know that 8 mm = 0.8 cm.
White fabric to coloured fabric =
1.5 to 0.8
1.5/0.8
This can be expressed as 15/8 or as a mixed number in the form 1_(7/8).
