Quandaries
and Queries
Hi! I am looking for an easy way to solve this type of question: Jim is travelling from Toronto to Ottawa, a distance of 435 miles. He travels part of the way at a speed of 100 km/h and because of an accident, he uses a secondary road and travels at 70 km/h. If the trip took him 6.5 hours, how far did he travel on each of the two roads.
Thank you for your help. I am a retired teacher who does tutoring for students from Gr.1 through Gr.11.

Hi Eleanor,
If he did x km (not 435 miles I presume) at 100km/h he did 435 - x at 70 km/h thus
x/100 + (435-x)/70 = time.
