Answer:
5 mph
Step-by-step explanation:
c+15+c=2c+15 mph going down stream.
2.4(2c+15)=60
4.8c+36=60
4.8c=24
The number may be 6 because 6 • 3 = 18, and 2 more than 18 would be 20
R = S = 82
360 - 82 - 82 = 196
196/2 = 98
Q = T = 98
6^2 is 36. / 3 makes 12. 12+6 is 18. final answer, most likely 18.
