Distance problem? |
I forgot how to do this problem so: Half Done trail at Yosemite Park is 26.9 km round trip. Scale of 2.5 cm (or is it 25?)=3 km. How many centimeters long is the trail of the map. I will try but you need to ask the question better. This is a ratio problem. roundtrip=26.9 km halfdone=13.5km. lengthoftrailonmap=2.5 cm(or25) roundtrip 3km by substitution lengthoftrailonmap=2.5cm(or25) 26.9km 3km 26.9km x lengthoftrailonmap=2.5cm(or25) x 26.9km 26.9km 3km cancel and divide lengthoftrailonmap=2.5cm(or25) x8.6=21.5cm(or215) or did you want the length of the halfdone trail on the map. Half the above answer. The trail is 26.9 km, which can be rounded to 27. With a scale of 2.5cm=3km, dividing 27 km by 3 is 9, and 9 x 2.5 = 22.5 cm. well, round trip. so half is 13.45km. then find out how many threes there are in that. take that answer then multiply by 2.5. 13.45 divide by 3 equals approx. 4.48 4.48 times 2.5=11.2 cm hope that helps |
