When Gabe drives from Sacramento to Redding it takes him 2.2 hours. It takes Elsa 2 hours to drive the same distance. Elsa's speed is 7 mph faster than Gabe speed. Find Gabe's speed and Elsa speed

Respuesta :

Answer:

Gave’s speed: 70 mph

Elsa’s speed 77 mph

Step-by-step explanation:

d = rt (distance = rate(speed) * time)

Gave d = 2.2r

Elsa d = (r+7)2

Distance was the same for both.

2.2r = 2r + 14

2.2 - 2r = 14

0.2r = 14

r = 14/0.2

r = 70
