You can convert the number to a percent or $ ur own self.
Ohh and I am pretty sure that NO math teacher maked u answer these types of problems!! :D
Let m and r represent the maximum speeds of Malcolm and Ravi in km/h, respectively.
... (m + r)/2 = 260 . . . . . the average of their speeds was 260 kph
... 2m = r + 80 . . . . . . . . double Malcolm's speed is 80 kph more than Ravi's
The second equation can be solved for r and that expression substituted into the first equation.
... 2m - 80 = r . . . . . . . . . . . an expression for r from the second equation
... (m + 2m - 80)/2 = 260 . . . the result of substituting that into the first
... 3m - 80 = 520 . . . . . . . . multiply by 2
... m = 200 . . . . . . . . . . . . . add 80 and divide by 3
... 2·200 - 80 = r = 320 . . .substitute the value of m into the expression for r
Malcolm's maximum speed was 200 km/h.
Ravi's maximum speed was 320 km/h.
(B)
Explanation:
4 quarts are in a gallon so one gallon equals 4(1). The one represents the amount of gallons so if there are x gallons it would become 4(x)
5 and 6 both go into 30
4/5= 24/30
1/6= 5/30
24/30-5/30= 19/30
