Answer: C.)T+10 mph= 60 mph
Step-by-step 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.
