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:
i=1
Step-by-step explanation:
i=(4*(1/2)i-1)
i=2i-1
i=1
Answer:
It will take 5 weeks for Brent to catch up with Marc.
Step-by-step explanation:
Given that:
Brent knows 10 of his lines and he can memorize 8 in a week.
Marc knows 25 of his lines and can memorize 5 in a week.
L = 8w + 10 Eqn 1
L = 5w + 25 Eqn 2
As the number of lines are same,
Eqn 1 = Eqn 2
8w + 10 = 5w + 25
8w - 5w = 25 - 10
3w = 15
Dividing both sides by 3
w = 5
Hence,
It will take 5 weeks for Brent to catch up with Marc.
