Answer:
Rate = (4C)cars/3(H)hrs
Step-by-step explanation:
Kelly can tune 4 cars in 3 hours.
The rate at which he dies work = 4/3
Thanks rate at which he tunes cars = 4/3 cars/hr
The expression of the above formula for C fraction of 4 cars and H fraction of 3 hours will be 4(C)/3(H)
Rate = (4C)cars/3(H)hrs
