Artemon [7]

Answer:

46 mph and 61 mph

Step-by-step explanation:

Distance=speed*time

Let speed of one bus be x and another x+15

After 3 hours

First bus would have traveled 3x while second bus 3(x+15)=3x+45

Total distance= 3x+3x+45=6x+45

6x+45=321

6x=321-45=276

x=276/6=46 mph

x+15=46+15=61 mph

Zina [86]

Answer:

$60^{\circ}$

Step-by-step explanation:

From the given figure it is clear that the stop board is a regular hexagon and ∠I is an exterior angle of the regular hexagon.

Exterior angle of a regular polygon with n sides $=\dfrac{360^{\circ}}{n}$

In a regular hexagon number of sides: n =6

Exterior angle of a regular hexagon $=\dfrac{360^{\circ}}{6}=60^{\circ}$

Since ∠I is an exterior angle of the regular hexagon, therefore, $\angle I=60^{\circ}$ .
