Answer:
Average speed is 48 km per hour
Step-by-step explanation:
A student drove to the university from her home and noted that the odometer reading of her car increased by 16.0 km. The trip took 20.0 min. (a) What was her average speed? in km/hr
Distance traveled is 16 km and the time taken is 20 minutes
convert minutes into hour. to convert minutes into hour we divide by 60 because 1 hour = 60 minutes
so time = 1/3 and distance = 16
Average speed = distance by time
Average speed is 48 km per hour
Answer:
1% of 4000 + 4% of B = 2% of (4000 + B)
40 + 0.04*B = 0.02( 4000 + B)
40 + 0.04* B = 80 + 0.02*B
40 + 0.04*B - 80 - 0.02B = 0
0.02*B - 40 = 0
0.02*B = 40
2B = 4000
B = 2000

Answer:
Step-by-step explanation:
-4 + (5+6/ -6 × 5) -2
Solve the brackets first!
-4 + (11/ -30) -2
Add the -4 and -2
-6 + (-11/30)
[If you meant -2 multiplied by (-11/30) then , something like this, If not then continue after the bracket!:
-4 + (11/15)
(-60+11)/15
-49/15 Answer ]
Now,
-6 -11/30
(-180-11)/30
-191/30
Hope this helps!
