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.
