I don't think it's proportional, because in order for a question to be a proportional question has/could be to be like this:
Gasoline costs $2.79 per 2 gallon. How much will it cost for 8 gallon. Then, we cross multiply and all to find the answer.
You're forgetting to add how many miles did the taxi drove you, without it, this problem doesn't have a solution, you're not including how many miles were drove additionally, as well as how much money you carry in the first place bud sorry
To find the time in which all the bells ring together, we need to find the LCM of 36,40,48.
Prime factorization of 36=2×2×3×3
Prime factorization of 40=2×2×2×5
Prime factorization of 48=2×2×2×2×3
Hence, LCM of 36,40,48=2×2×2×2×3×3×5=720 seconds.
720seconds=
60
720
minutes=12minutes
Hence, all the bells will ring together after 12 mi
