A scooter travels 10 miles per hour faster than an electric bicycle. The scooter traveled for 3 hours, and the bicycle traveled 5 1/2 hours. Altogether, the scooter and bicycle traveled no more than 285 miles. Find the maximum speed of each.

Please help someone ASAP!!

Bicycle: 30 miles/hour

Scooter: 40 miles/hour

Step-by-step explanation:

Let the speed of the bicycle be s,

Then the speed of the scooter is:

s + 10

Distance = speed × time

Distances covered:

Bicycle: (s)(5½) = 5.5s

Scooter: (s + 10)(3) = 3s + 30

Total:

5.5s + 3s + 30

8.5s + 30

8.5s + 30《285

8.5s《255

s《30

s + 10《40

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
