+73 Santi and Vlado drove together from NY to New Orleans. Both drove the same amount of time, but Santi drove 75% as quickly as Vlado. If the drive took a total of 24 hours and New Orleans is 1304 miles from NY, approximately how many miles did Santi drive?
A 326
B 560
C 744
D 978
I thought it was 978 but it isnt. This trick question' explianation behind the correct answer B doesn't make any sense to me...... Somebody help?
Hoold up I just realized something, at first I thought they are driving at the same time with differentcar, but now it just appears to be they just carpool and take turns driving the car. Is this it?
+128475 So each drove 12 hrs
And Rate * Time = Distance
So...call Vlado's rate R and Santi's rate (.75R) and we have
Santi's Rate * Time Driving + Vlado's Rate * Time Driving = Total Distance
.75R (12) + R(12) = 1304 simplify
R(9) + R(12) = 1304
R (21) = 1304 divide both sids by 21
R ≈ 62.1 mph
So Santi drove ≈ .75 (62.1) (12) ≈ 559 miles ⇒ round to 560 miles
+128475 Yep...taking turns driving is the way I interpret it...each drives 12 hours
Here is another way:
1304/24 =54 1/3 miles - average speed of both men
[54 1/3 x 2] / 1.75 =~62 miles - average speed of Vlado
62.1 x 0.75 =~46.7 miles - average speed of Santi
12 hours x 62 =~744 - miles driven by Vlado.
12 hours x 46.7 =~560 - miles driven by Santi.
