Let the speed of the bus be x,
Distance = speed × time
(90+x) (16:20 –13:20) = 510
=> 3(90+x) = 510
=> 270 + 3x = 510
=> 3x = 510–270
=> x = 240/3
=> x = 80
Thus, the speed of the bus is 80km/hr.
Answer: -16
Step-by-step explanation:
4m-15m-50=126
-11m=126+50
-11m=176
m=176/-11
m=-16
Answer:
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches
Step-by-step explanation:
( area can be found with the formula l × w [length × width] )
I will call the width "x"
w · l = 72
x · x + 5 = 72
- 5 - 5
x · x = 67
x² = 67
√x² = √67
x ≈ 8.185
(x = √67)
so, by adding 5 inches, we get that
x + 5
8.185 + 5 [√67 + 5]
length = 13.185
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches
