45x=70x54 - cross multiply
x=70x54/45 - divide by 45
x=84
Keisha ran 2.4 miles more than Jamal.
Keisha ran 8.5 miles, how many miles did Jamal run?
m = the number of miles Jamal ran
2.4 + m = 8.5
[Keisha ran 2.4 more miles than Jamal(m), she ran a total of 8.5 miles]
2.4 + m = 8.5 Subtract 2.4 on both sides
m = 6.1
Jamal ran 6.1 miles (Your answer is the 2nd option)
100 is the smallest number they will all go into, so 100
Well, the speed is 45mph (divided 270 by 6). It would take her 9 hours (divided 405 by 45).
