That's between 24/3 and 27/3 i.e. between
1b. Answer: 8 and 9
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
2x + 4 > 8
Step 1: Subtract 4 from both sides.
2x + 4 − 4 > 8 − 4
2x > 4
Step 2: Divide both sides by 2.
2x/2 > 4/2
x > 2
2x − 3 < 5
Step 1: Add 3 to both sides.
2x − 3 + 3 < 5 + 3
2x < 8
Step 2: Divide both sides by 2.
2x/2 < 8/2
x < 4
10 plays
Divide 2/5 and 4 by 2 to get 1/5 and 2
For every 1/5 of practice he teaches the ten 2 plays
5/5 = 1
So 5*2 = 10 plays
