Tanya [424]3 years ago
4 0

Answer:

Step-by-step explanation:

add up their speed.

combined speed = x+ 1 x + 10

( 2 x + 10 )

Time = 5 hours

Distance = 750 miles

Distance = speed * time

( 2 x 10 )* 5 = 750

10 x + 50 = 750

10 x = 750 + -50

10 x = 700

/ 10

x= 70 mph Car A

Car B 70 + 10 = 80 mph
