(4) 1. For each of the following, which is the greater unit rate (not the better deal, the greater unit rate)? a) $3.25 for 526 mL or $8.45 for 1.2 L (2 marks) b) 45 km/h or 30 mph (2 marks) Communication tip 1 mi (mle)-167 km 1US gal-379L (4) 2. Nuri is researching the fuel efficiency of pickup trucks. He found a website that advertised a hybrid pickup truck with a fuel efficiency of 22 mpg for highway driving. He found another website that advertised a pickup truck with a fuel efficiency of 10 km/L for highway driving Which truck has a better fuel efficiency? Explain how you know. 3. Draw a graph to represent hiking 500 m from a campground in 10 min, stopping for 5 min, hiking another 400 m away from the campground in 8 min, and then hiking back to the campground along the same trail in 15 min. Where appropriate, assume you are travelling at a constant rate on each part of the trip. (5) Then, determine the rate for each portion of the graph.
