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
We know, Circumference of a Circle = 2πr
In mathematical form, You can write it as:
2πr₁ = 3(2πr₂)
2π(12) = 6πr₂
24π = 6πr₂
r₂ = 4 m
In short, Your Answer would be: 4 meter
Hope this helps!
