Question from Rachelle, a parent: We are taking a trip from Ottawa, ON to Toronto, ON. The total trip is 150 kms and will take us 4.5 hours. We have already driven 108 kms and there is still 42 kms left to go. If we are travelling 110 kms/hr, how much longer will it take to reach Toronto? |
Hi Rachelle,
If you are travelling 110 kilometres every hour then you travel 1 kilogram in 1/110 = 0.009 hours. How long does it take to go 42 kilometres?
