1 day equals 24 hours.
18 hours / 24 hours = 0.75 days
The total days is 5.75 days.
Multiply the amount the bulb uses in 1 day by 5.75 days:
3600 x 5.75 = 20,700 watt-hours.

Answer:
46 i think because 20+26 is 46
Answer:
32 miles
Step-by-step explanation:
Given data
Let the total distance be x miles
Marks speed= 16miles per hour
Trisha's speed= 12 miles per hour
Trisha has covered 8 miles and has (x-8) miles to finish line
We know that
Speed= distance/time
time= distance/speed
Hence the time taken for Mark to finish is
time= x/16---------------1
The time taken for Trisha to finish is
time= (x-8)/12-----------2
equate 1 and 2 above
x/16= (x-8)/12
cross multiply
16(x-8)= 12*x
16x-128= 12x
collect like terms
16x-12x= 128
4x=128
x= 128/4
x= 32 miles
Hence they will meet at exactly 32 miles along the way
It would take Carlos 2 hours to walk 8 miles because 4 * 2 = 8.
