Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h
Step-by-step explanation:
Lets assume Malcolm maximum speed to be M km/h and Ravi maximum speed to be R km/h
Average of their maximum speed is; (M+R)/2 =260 km/h
This can be simplified to M+R= 260*2
M+R = 520.......................................(I)
When Malcolm's speed is doubled,
2M=R+80 km/h ----------------------(ii)
The two equations are;
M+R = 520 ------ M=520-R ----(i)
2M=R+80 ---------------------------(ii)
Replacing M with (i) above
2M=R+80
2(520-R) =R+80
1040 -2R =R+80
1040-80 = R+2R
960 = 3R
960/3 =R
320 =R
M+R =520
M=520-320 =200
Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h

Answer: Take the bus to save money
Step-by-step explanation:
you plug x for 15, the inequality would be ($0.50 * 15) + $3 < $10. We need a less than sign (<) because Carl says the price has to be under and not equal to.
$7.5 + $3 < $10. After you do simple math and add, you will know that Carl is short of money by 50 cents.
Hope this helps :)
