It takes Ricky, traveling at 24 mph, 45 minutes longer to go a certain distance than it takes Maria traveling at 51 mph, Find th

klio [65]

Answer:

85 mi

Step-by-step explanation:

Let d = the distance in miles traveled

Let M = the time in hours for Maria to travel d miles

$m+\frac{3}{4} =$ time in hours for Ricky to travel d miles

(Note that $\frac{3}{4}$ hrs = 45 min)

----------------------

Maria's equation:

d = 51m

Ricky's equation:

d = 24 · $(m+\frac{3}{4} )$

----------------------

Substitution:

51m = 24 · $(m+\frac{3}{4} )$

51m = 24m + 45

6m = 10

m = $\frac{5}{3}$

----------------------

d = 51m

d = 51 · $(\frac{5}{3})$

d = 85

----------------------

The distance traveled is 85 mi
