Question 972288: To reach certain place,A has to drive 10% more distance than B .If B drives at speed which is 20% slower than A ,Determine the ratio of time taken by A to time taken by B to reach destination. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! To reach certain place, A has to drive 10% more distance than B.
If B drives at speed which is 20% slower than A,
Determine the ratio of time taken by A to time taken by B to reach destination.
:
let d = the distance driven by B
then
1.1d = the distance driven by A (travels 10% more)
:
let s = speed driven by A
then
.8s = speed driven by B (20% slower)
:
time = dist/speed
Time ratio A:B: = * = 1.1 * .8 = .88 (Canceled d and s)
Ratio can be written and then reduced = is the time ratio of A To B
