if mikayla drove 19 miles in 18 minutes along a highway stretch approximately how far did she drive in 90 minutes along the same stretch?

Question

i feel like the answer i get is wrong

Answer 1

The assumption in this problem is that Mikayla drives at a constant rate. Therefore, we can set up a proportion.

 

19/18 = m/90, where m = the number of miles driven in 90 min.

 

Cross-multiplying gives us:

 

18m = 1710

m = 95 miles
