Achevy is traveling 10 mph faster than a toyota. the chevy is traveling at a rate of 60 mph.
let t = the the speed of the toyota.
which formula below would correctly calculate the speed of the toyota?
a.)t+(t-10 mph)= 60 mph
b.)t-10 mph=60 mph
c.)t+10 mph= 60 mph
d.)t+ (t+10 mph)= 65 mph

C.)T+10 mph= 60 mph

Explanation:

Given : A Chevy is traveling 10 mph faster than a Toyota.

i.e. (speed of Toyota) +(10mph) = (speed of of Chevy)

If T = the speed of the Toyota and the speed of Chevy = 60 mph.

Then , we get

T+10 mph = 60 mph

Thus , the formula correctly calculate the speed of the Toyota would be :

T+10 mph = 60 mph

Hence, the correct option is C.)T+10 mph= 60 mph.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
