Answer:
A=a+b
2h=10+20
2·6=90
Step-by-step explanation:
HAVE A GREAT DAY
Day = 24 hours, right?
36000/24 = 1500
If I put this into words:
36000 people per 24 hours = 1500 people per 1 hour
On average, 1500 people ride the bus per hour (or each hour)
Answer:
2.4 hours
Step-by-step explanation:
Let total work = X
Rate of work done = X ÷ time
Rate of A = X/4
Rate of B = X/6
If they work together, rate is the sum of their individual rates, i.e.
X/4 + X/6
= (3X + 2X)/12 (taking LCM)
=5X/12
Rate = X/time
5X/12 = X/time
time = X÷(5X/12)
time = X × 12/(5X)
time = 2.4 hours
Shortcut:
Product of individual times/sum of individual times
= (4×6)/(4+6)
=24/10
=2.4 hours
The answer to your question is 2/7 is 1/2 of 1 3/4.
