Answer 24

Answer 25

haha nice

Answer 26

My method is very complicated though... so take what you can from it.


For every 1 km that Jasmine travels,
Chelsea will travel 0.523 km. Therfore ratio of Chelsea to Jasmine is 523:1000.
59.4 /1523 = Distance travelled
Chelsea distance travelled = 20.398 km ~ 20.4km
Jasmine distance travelled = 39.002 km ~ 39.0km

Time = Distance / Speed

Jasmine
Time = 39/65

Chelsea
Time =20.4/34

Time for Chelsea and Jasmine should be the same, which if you work it out the calculations... They both equal 0.6 hours (36 minutes)

Answer 27

im doing algebra 1 so i don't know it should just be some variation of d=rt
